By comparing its set of factors to another set of factors.
The greatest common factor of two numbers has to show up on the lists of factors of both numbers.
The factors of 184 are: 1, 2, 4, 8, 23, 46, 92, 184 The factors of 207 are: 1, 3, 9, 23, 69, 207 The common factors are: 1, 23 The Greatest Common Factor: GCF = 23
A common factor.
List the factors. 1,7 1,2,4,5,10,20 The only, and therefore the greatest common factor is 1.
A factor rainbow will show all of the factors. A factor pair is just 2 numbers that are factors of the number you want to find.
The factors of 15 are:1, 3, 5, 15The factors of 305 are:1, 5, 61, 305The GCF is 5.
The factors of 12 are:1, 2, 3, 4, 6, 12The factors of 20 are:1, 2, 4, 5, 10, 20The common factors are:1, 2, 4The Greatest Common Factor:GCF = 4

The factors of 126 are: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126 The factors of 154 are: 1, 2, 7, 11, 14, 22, 77, 154 The common factors are: 1, 2, 7, 14 The Greatest Common Factor: GCF = 14
A factor of a number is any number into which the original number can divide evenly. Thus the factors of 40 are: 1, 2, 4, 5, 8, 10, 20 and 40. The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18 and 36. The common factors are any numbers that show up in both lists. In this case, the common factors of 40 and 36 are 1, 2 and 4.
