Least Common Multiple

Find the LCM of Two Numbers

LCM of 8 and 12 is 24
Calculate

The least common multiple is the smallest positive integer that is divisible by both values. So enter the both value in given input box, then press calculate button, the system will automatically calculate the LCM value of those numbers.

To find LCM (Least Common Multiple) between two numbers, mainly there are two methods available, Those are-

1. GCF Method: To find the LCM value using GCF method, use the simple formula-

lcm(a,b) =
(a × b)/gcf(a,b)

Where,

  • a = First integer value;
  • b = Second integer value;
  • gcf = Greatest common factor;

2. Prime Factorization Method: Find the prime factors of both number and then multiply of all the highest exponent prime factors value, you will get the LCM value.
