Question

What Is Meant By Common Factor

Answer 1

Answer:

Step-by-step explanation:

"Factors" are numbers we can multiply together to get another number.

When we find the factors of two or more numbers, and then find some factors are the same ("common"), then they are the "common factors".

Example: 12 and 16

• The factors of 12 are: 1, 2, 3, 4, 6 and 12

• The factors of 16 are: 1, 2, 4, 8 and 16

So the common factors of 12 and 16 are: 1, 2 and 4

Answer 2

The greatest number that is a factor of two (or more) other numbers.

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

Abbreviated "GCF". Also called "Highest Common Factor"
