LCM of 68, 42, 28, 380

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

LCM of:

Least Common Multiple of 68,42,28,380

Least Common Multiple (LCM) of 68,42,28,380 is 135660

2 68, 42, 28, 380
2 34, 21, 14, 190
7 17, 21, 7, 95
17, 3, 1, 95

∴ So the LCM of the given numbers is 2 x 2 x 7 x 17 x 3 x 1 x 95 = 135660

Least Common Multiple of 68,42,28,380 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 68,42,28,380 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,42,28,380) = 2

common factors(in case of two or more numbers have common factors) = 112

GCF(68,42,28,380) x common factors =2 x 112 = 224

LCM(68,42,28,380) = ( 68 × 42 × 28 × 380 ) / 224

LCM(68,42,28,380) = 30387840 / 224

LCM(68,42,28,380) = 135660

∴ Least Common Multiple of 68,42,28,380 is 135660
