LCM and GCD

About: LCM and GCD

You can use this app to calculate the least common multiple and the greatest common divisor of a series of numbers. You can enter the number in the input on the top separated by a space or a comma and the app will automatically calculate the least common multiple (lcm) and the greatest common divisor (gcd) for you.

The least common multiple (lcm) is the smallest positive integer that is divisible by all numbers in the series. e.g. the lcm of 24 and 80 is 240. 240 is the smallest number that can be divided by both 24 and 80.

The greatest common divisor (gcd or gcf) is the largest positive integer that divides each of the integers. e.g. the gcd of 24 and 80 is 8. Both 24 and 80 can be divided by 8 and there is no larger integer that divides both 24 and 80.
