The first step to this method of finding the Greatest Common Factor of 32 and 58 is to find and list all the factors of each number. Again, you can see how this is done by looking at the “Factors of” articles that are linked to above.
Let’s take a look at the factors for each of these numbers, 32 and 58:
Factors of 32: 1, 2, 4, 8, 16, 32
Factors of 58: 1, 2, 29, 58
When you compare the two lists of factors, you can see that the common factor(s) are 1, 2. Since 2 is the largest of these common factors, the GCF of 32 and 58 would be 2.
