The GCF is 1.
Since 32 is a factor of 256, it is automatically the GCF.
The greatest common factor (gcf) of 28 and 36 is 9.
To find the highest common factor of two numbers, you must first split them into their prime factors. In this case, the numbers 28 and 32 can split as follows: 28 = 2x2x7 32 = 2x2x2x2x2 The next step is to identify all common prime factors. In this case, the common prime factors are two 2s. To find the HCF, you just multiply these together: 2x2=4 Thus the highest common factor of 28 and 32 is 4.
The greatest common factor of 28 and 72 is 4.

Factors of 16: 1, 2, 4, 8, 16 Factors of 28: 1, 2, 4, 7, 14, 28 Factors of 32: 1, 2, 4, 8, 16, 32 GCF (16, 28, 32) = 4
To find the highest common factor of two numbers, you must first split them into their prime factors. In this case, the numbers 28 and 32 can split as follows: 28 = 2x2x7 32 = 2x2x2x2x2 The next step is to identify all common prime factors. In this case, the common prime factors are two 2s. To find the HCF, you just multiply these together: 2x2=4 Thus the highest common factor of 28 and 32 is 4.
You need at least two numbers to find a GCF. If that's 32, 40 and 28, the GCF is 4.
