### What are the factors of GCF?

For a set of numbers their GCF shares the factors which have the set of numbers in common. e.g. Let us consider two numbers: 36 and 24. GCF of 36 and 24 is 12 and the factors of 12 are 1, 2, 3, 4, 6 and 12. Factors of 24: 1, 2, 3, 4, 6, 12 and 24. Factors of 36: 1, 2, 3, 4, 5, 6, 9, 12 and 36. Common factors of 24…

### What factors of 36 are not factors of 18?

To answer this question you first need to isolate the prime factors in each number. In this case the numbers are 36 and 18 so the prime factors are: 18 = 2x3x3 36 = 2x2x3x3 The next step is to identify any unique factors. In this case, the only prime factor 36 has which 18 doesn't is a second 2. Thus any combination of the prime factors of 36 which includes both 2s will not…
