What is the LCM of 540 and 315?

Answer 1

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.

Prime factorization of 540 = 2x2x3x3x3x5

Prime factorization of 315 = 3x3x5x7

HCF(540, 315) = 3x3x5 = 45.

2- Product of 540 and 315.

540 x 315 = 170100.

3- LCM(540, 315) = 170100/45 = 3780.

Answer 2

The LCM is 3780.
