To determine the greatest common factor (GCF) between a set of numbers, let's first break down each of the given numbers into their prime factors. We will also take note of all prime factors that are common between each of the given numbers.
Given number
Prime Factorization
12
2* 2* 3
18
2* 3* 3
For the given values, the common prime factors are: 2 and 3. Calculating the product of these factors will give us the GCF of the given set.
2* 3 = 6
