For Greatest Common Factors to exist, there need to be two or more numbers to compare.

Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF

All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. If you compare the lists of factors, you will see which ones are common.Example: 30 and 421, 2, 3, 5, 6, 10, 15, 301, 2, 3, 6, 7, 14, 21, 42The common factors are 1, 2, 3, 6

Common factor questions will give you some numbers (usually two, but can be more) and ask you to find the common factors. Example: 30 and 42 List the factors of each number. 1, 2, 3, 5, 6, 10, 15, 30 1, 2, 3, 6, 7, 14, 21, 42 Write down the numbers that appear on both lists. 1, 2, 3 and 6 are the common factors of 30 and 42.

What is the greatest common factor of 30, 42, and 48?2368Correct Answer:"6"You answered this question correctly!ExplanationThe greatest common factor of two or more whole numbers is the largest whole number that divides evenly into each of the numbers. We'll work this out by writing the factors of 30, 42 and 48:Factors of 30The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30Factors of 42The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42Factors of 48The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48By looking at the lists, we can see that the greatest common factor of 30, 42 and 48 is 6.
