Frequently Asked Questions
What are common factors?
Common factors, also known as common divisors, are numbers that divide evenly into two or more different numbers without leaving a remainder. For example, the common factors of 12 and 18 are 1, 2, 3, and 6.
How do you find common factors?
To find common factors of two or more numbers: 1) List all factors of each number, 2) Identify the factors that appear in all lists. These are your common factors. Alternatively, you can use the prime factorization method to identify common prime factors.
What is the difference between common factors and the greatest common factor (GCF)?
Common factors are all the numbers that divide evenly into two or more numbers. The greatest common factor (GCF) is the largest of these common factors. For example, the common factors of 12 and 18 are 1, 2, 3, and 6, with 6 being the GCF.
