LCM of 12, 21, 76, 156

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

LCM of:

Least Common Multiple of 12,21,76,156

Least Common Multiple (LCM) of 12,21,76,156 is 20748

2 12, 21, 76, 156
2 6, 21, 38, 78
3 3, 21, 19, 39
1, 7, 19, 13

∴ So the LCM of the given numbers is 2 x 2 x 3 x 1 x 7 x 19 x 13 = 20748

Least Common Multiple of 12,21,76,156 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 12,21,76,156 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,21,76,156) = 1

common factors(in case of two or more numbers have common factors) = 144

GCF(12,21,76,156) x common factors =1 x 144 = 144

LCM(12,21,76,156) = ( 12 × 21 × 76 × 156 ) / 144

LCM(12,21,76,156) = 2987712 / 144

LCM(12,21,76,156) = 20748

∴ Least Common Multiple of 12,21,76,156 is 20748
