What is the GCF of 4 and 4? | Thinkster Math? ›

When you compare the two lists of factors, you can see that the common factor(s) are 1, 2, 4. Since 4 is the largest of these common factors, the GCF of 4 and 4 would be 4.

Explanation: another approach is to list the factors out and pick out the common ones. Factors of 4:{1,2,4}

In this case, the greatest common factor is 4.

What are the Factors of 4? The factors of 4 are 1, 2 and 4.

Factors of 4: 1, 2, and 4.

LCM of 4 and 4 is 4.

The GCF of 2 and 4 is 2. To calculate the greatest common factor (GCF) of 2 and 4, we need to factor each number (factors of 2 = 1, 2; factors of 4 = 1, 2, 4) and choose the greatest factor that exactly divides both 2 and 4, i.e., 2.

Factors of 4 in Pairs

The factors of 4 are: 1, 2, 3, and 4. The factors of other numbers are: 5, 6, 7, 8, 9, 10. The factors of other pairs are: (2x), (3x), (4x), and so on.

The GCF of 4 and 10 is 2. To calculate the greatest common factor (GCF) of 4 and 10, we need to factor each number (factors of 4 = 1, 2, 4; factors of 10 = 1, 2, 5, 10) and choose the greatest factor that exactly divides both 4 and 10, i.e., 2.

For example, 4 is a factor of 8, 12, 16, 20, etc. because 8 ÷ 4 = 2, 12 ÷ 4 = 3, 16 ÷ 4 = 4, 20 ÷ 4 = 5, etc.; therefore, all the numbers in the 4 times tables have 4 as a factor.

Can 4 be a factor of 4? ›

All perfect square integers have an odd number of positive integer factors. For 4 they are 1, 2 and 4.

And 4 also has exactly three factors: 1, 2, and 4.

Since, 4 has three factors, i.e., 1, 2, 4, therefore 4 is a composite number.

Factors of 100 = 1, 2, 4, 5, 10, 20, 25, 50, and 100.

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.

The factors of 12 are 1, 2, 3, 4, 6, and 12, because each of those divides 12 without leaving a remainder (or, alternatively, each of those is a counting number that can be multiplied by another counting number to make 12).

To find the GCF of a set of numbers, list all the factors of each number. The greatest factor appearing on every list is the GCF. For example, to find the GCF of 6 and 15, first list all the factors of each number. Because 3 is the greatest factor that appears on both lists, 3 is the GCF of 6 and 15.

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators.

What are the factors and multiples of 4? The factors of 4 are 1, 2 and 4. The multiples of 4 include 4, 8, 12, 26, 20, 24, 28, 32, 36, 40, 44, etc.

For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.
