A Euclidean Algorithm Calculator is a free online mathematics tool that uses the Euclidean algorithm to find the Greatest Common Divisor (GCD) of two or more integers.
The GCD is the largest positive integer that divides two numbers without leaving a remainder.
How Does the Euclidean Algorithm Work?
The Euclidean algorithm repeatedly divides the larger number by the smaller number and replaces the numbers with the divisor and the remainder.
For example, to find the GCD of 48 and 18:
- 48 ÷ 18 = 2 remainder 12
- 18 ÷ 12 = 1 remainder 6
- 12 ÷ 6 = 2 remainder 0
When the remainder becomes 0, the last non-zero remainder is the GCD.
GCD(48, 18) = 6

Euclidean Algorithm Formula
The basic relationship is:
GCD(a, b) = GCD(b, a mod b)
The process continues until the remainder equals zero.
