List the factors.
1, 2, 4, 7, 14, 28
1, 2, 4, 8, 16, 32
Select the factors on both lists.
1, 2 and 4 are the common factors.
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 GCF is 4.
The greatest common factor (gcf) of 28 and 36 is 9.
No, 2 is a common factor of all even numbers but not necessarily the greatest common factor. Take 40 and 32: 40:1,2,4,5,8,10,20,40 32:1,2,4,8,16,32 8 is the greatest common factor of these two even numbers.
The greatest common factor of 4225 and 32 is 1
4 is the highest common factor of 28 and 32
4 is a factor of 28. 4 is a common factor of 28 and 32.
The least common factor is: 1
1 and the highest common factor is 4
