Lowest Common Multiple Calculator

The Lowest Common Multiple (also known as the Least Common Multiple) of 2 natural numbers a and b, lcm(a,b), is the smallest integral which is divisble number by both numbers.

One of the simplest methods of determining the lcm is to multiply the 2 numbers together, and then divide by the Greatest Common Divisor (gcd) of the same numbers.

Factorizing both numbers will make the division easier.

For example, to find the lcm of 24 and 36:

lcm(a,b)	=	a  x  b	:	24  x  36	=	2 x 2 x 2 x 3  x  2 x 2 x 3 x 3s	=	72
		gcd(a,b)		12		2 x 2 x 3
