The Greatest Common Factor (GCF) is the largest number that is a common factor of two or more numbers.

How to find the greatest common factor:

• Determine if there is a common factor of the numbers. A common factor is a number that will divide into both numbers evenly. Two is a common factor of 4 and 14.
• Divide all of the numbers by this common factor.
• Repeat this process with the resulting numbers until there are no more common factors.
• Multiply all of the common factors together to find the Greatest Common Factor
