Steps to find out LCM of two numbers(a & b):
1- Find HCF of a & b.
2- Multiply a and b.
3- Divide the result of step 2 by HCF. The result is LCM.
1- In order to find out HCF of 540 and 315 we shall use the method of prime factorization.http://wiki.answers.com/What_is_the_LCM_of_540_and_315#ixzz1N04Gck00
Prime factorization of 21 = 3x7
Prime factorization of 80 = 2x2x2x2x5
So, HCF(80, 21) = 1
2- Product of 80 and 21.
80 x 21 = 1680
3- LCM(80, 21) = 1680/1 = 1680
