What are factors in math?

factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder . For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

What is the meaning of factors?

A factor is an element that influences something , like many factors that contribute to global warming. To factor means to consider something relevant when making a decision or conclusion, like factoring in the weather and traffic when figuring out how long the drive will be.

What are 5 examples of factors?

What Is a Factor in Math? Product Factors 2 × 4 = 8 Both 2 and 4 are factors of 8. 2 × 3 = 6 Both 2 and 3 are factors of 6. 9 × 3 = 27 Both 3 and 9 are factors of 27. 7 × 5 = 35 Both 5 and 7 are factors of 35. 1 more row

Why is 5 a factor of 20?

5 is a factor of 10, 15, 20, 25, etc. because 10 ÷ 5 = 2, 15 ÷ 5 = 3, 20 ÷ 5 = 4, 25 ÷ 5 = 5 , etc.; therefore, all the numbers in the 5 times table have 5 as a factor.

How to find the factors?

We can find all the factors of any counting number by systematically dividing the number by each counting number, starting with 1 . If the quotient is also a counting number, then the divisor and the quotient are factors of the number.

How do you explain factors to a child?

A factor is a number that fits exactly into a given number, or divides a particular number with no remainder (fraction or decimal) . They can also be identified as pairs of numbers that multiply together to make another number. A factor is always a positive integer (whole number).

Why do we factor in math?

Sometimes, factoring allows us to simplify expressions, or write them in a form that is easier to use or interpret in some way . This is especially true when the expression is a rational expression (a polynomial divided by a polynomial).

What is the factor method in math?

In the factorisation method, we reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets . The factors of any equation can be an integer, a variable or an algebraic expression itself.

Does 20 have 2 factors?

As 20 is an even composite number, it has many factors other than 1 and 20. Thus, the factors of 20 are 1, 2, 4, 5, 10 and 20 .

What is a factor of 36?

The factors of 36 are the numbers that divide 36 exactly without leaving any remainder. Thus, the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36 .

What are the factors of 16?

The factors of 16 are 1, 2, 4, 8 and 16 . Similarly, the negative factors of 16 are -1, -2, -4, -8 and -16.

Abiotic Factors

Abiotic factors are factors in the ecosystem that are not associated or derived from living organisms. In Yellowstone, abiotic factors include water, rainfall, sunlight, temperature, precipitation. Water affects the Yellowstone ecosystem because it is needed for all living things. Each organism needs water to survive. If water was removed from Yellowstone, the biotic factors of the park would perish. In Yellowstone, rainfall can dictates the type of plant growth in the area. Drought can decrease plant growth, which can affect Yellowstone’s food chain. A decrease in producers causes a decrease in food source for primary consumers. Sunlight is another important factor because it is also needed for life. Sunlight is needed for plants to grow and for other organisms to survive. An important factor in the Taiga biome is the temperature. The temperatures in Yellowstone dictate what types of organisms grow or reside in that area. The temperature can vary greatly in different parts of Yellowstone and can yield many different types of life. Many different organisms have ideal temperature ranges for living.

Biotic Factors

Elk in Yellowstone National Park

Biotic factors are factors that have to do with life or living organisms. One of the most important biotic factors in Yellowstone National Park is the elk. Elk are a keystone species in Yellowstone and is a very large portion of the ecosystem. The elk has many predators and serves to withstand a substantial portion of the wildlife in the park. Most notably, wolves and coyotes feed on the elk. A decrease in elk causes a decrease in its predator populations. Therefore, predation is another very important biotic factor of Yellowstone. Predation withstands populations and provides foods for many organisms. In addition, disease is another biotic factor that is important to Yellowstone’s wildlife. Many populations are affected by disease by a decrease in the number of organisms present.

Limiting Factors

Limiting factors are factors present in an environment that control the growth, abundance, or distribution of a population of organisms in an ecosystem. The two types of limiting factors are density independent and density dependent limiting factors.

Density-Independent Limiting Factors

Density-idependent limiting factors affect a population’s size and growth independent of population density. In Yellowstone, weather can influence wildlife populations. Temperature and moisture can cause populations to increase or decrease. Forest fires and drought typically cause population decrease. These factors may cause death rates of populations to increase and limit population growth. This change is independent of the number of individuals in a population, hence, they are density-independent.

Density-Dependent Limiting Factors

Density-dependent limiting factors affect the size and growth of a population based on population density. In Yellowstone, the competition for resources is a very important limiting factor. An increase in population size decreases the amount of available resources, which then limits the size and growth of a population. For example, an large increase in the wolf population limits the amount of elk that are available to feed on. In turn, the wolf population would decrease due to lack of resources. The competition for land space to establish territories is another density-dependent factor. This is a behavioral mechanism that could limit the amount of animals one area could hold, limiting population growth. High population densities may result in stress syndromes, which could potentially result in hormonal changes in some organisms. These hormonal changes may delay the onset of reproduction, which can limit the number of individuals in a population and the population growth. In addition, disease can spread rapidly in populations with higher densities. The spread of disease can cause many individuals in a population to die, which limits reproduction and population growth.
