Continuous Division

Continuous Division you can use a method called continuous division to find the greatest common factor (GCF) of a number. The GCF also deals with prime numbers. You can carry out continuous division by: 1) Writing down the two numbers you're trying to find the GCF of. 2) Draw an "L" shape surrounding them.

Using Division Method to Find GCF

• Step 1 - Divide the larger number by the smaller number using long division.
• Step 2 - If the remainder is 0, then the divisor is the GCF.
• Step 3 - If the remainder is 0, then the divisor of the last division is the GCF.
