MyCalculatorHow it works
We find the greatest common divisor (GCD) of A and B, then divide both by it.
Example
8:12 has a GCD of 4, simplifying to 2:3.
Assumptions & limitations
Works with positive whole numbers. Decimal inputs are rounded before simplifying.
Frequently asked questions
What if my numbers have decimals?
Round to whole numbers first, or scale both sides by 10, 100, etc. before entering.
