# How do you find the GCF of 28 and 36?

4

Find each number's factors.

36 = 1, 2, 3, 4,, 6, 9, 12, 18, 36. 28 = 1, 2, 4,, 7, 14, 28.

Next, find the highest number in each of the two sets of factors.

To find the greatest common factor (GCF) of 28 and 36, you can use the prime factorization method.

First, find the prime factors of each number:

- Prime factors of 28: 2 × 2 × 7
- Prime factors of 36: 2 × 2 × 3 × 3

Next, identify the common prime factors:

- 28 has 2 × 2 (two 2s)
- 36 has 2 × 2 (two 2s)

The common prime factors are 2 × 2, which equals 4.

Therefore, the greatest common factor (GCF) of 28 and 36 is 4.
