LCM of 15, 18, 11, 644

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 15,18,11,644

Least Common Multiple (LCM) of 15,18,11,644 is 318780

2 15, 18, 11, 644
3 15, 9, 11, 322
5, 3, 11, 322

∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 11 x 322 = 318780

Least Common Multiple of 15,18,11,644 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 15,18,11,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,18,11,644) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(15,18,11,644) x common factors =1 x 6 = 6

LCM(15,18,11,644) = ( 15 × 18 × 11 × 644 ) / 6

LCM(15,18,11,644) = 1912680 / 6

LCM(15,18,11,644) = 318780

∴ Least Common Multiple of 15,18,11,644 is 318780
