Modified Booth's Algorithm Example

Enter two whole numbers to find the greatest common factor (GCF). See the work and learn how to find the GCF using the Euclidean Algorithm.

How to Find the GCF Using Euclid's Algorithm

Given two whole numbers where a is greater than b, do the division a ÷ b = c with remainder R.
Replace a with b, replace b with R and repeat the division.
Repeat step 2 until R=0.
When R=0, the divisor, b, in the last equation is the greatest common factor, GCF.

Since greatest common factor (GCF) and greatest common divisor (GCD) are synonymous, the Euclidean Algorithm process also works to find the GCD.
