When you are finding common factors, one method is to list the factors.
All of them. Different numbers have different numbers of factors.
Factors are numbers you can multiply together to get another number. 30: 1, 2, 3, 5, 6, 10, 15, 30
2, 3, 5, 6, 10, 15
-- List all the factors of the first number.-- List all the factors of the second number.-- If there are more than two numbers, then list all the factors of each of the rest of them.-- Inspect the lists, to see what factors show up on every list.-- Pick the greatest factor that shows up on every list.
The list of factors of 50.
1, 2, 3, 5, 6, 10, 15, 30
All non-zero numbers have factors. These can be written down in a list. That would be known as a list of factors.
All Factors of 150:1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
Common factors of 18 and 30 are: 1, 2, 3, and 6.
find all factors of 72
All the factors of 30.
The product of all the common prime factors is the GCF. The product of all common factors would vary according to the list.
