How it works
Simplify Fractions Calculator is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.
Finding the greatest common factor
Divide the larger number by the smaller and keep the remainder; repeat with the smaller number and the remainder until the remainder is 0. The last number you divided by is the greatest common factor: 24 ÷ 18 leaves 6, and 18 ÷ 6 leaves 0, so it is 6.
