LCM of 30, 42, 42, 109

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

LCM of:

Least Common Multiple of 30,42,42,109

Least Common Multiple (LCM) of 30,42,42,109 is 22890

2 30, 42, 42, 109
3 15, 21, 21, 109
7 5, 7, 7, 109
5, 1, 1, 109

∴ So the LCM of the given numbers is 2 x 3 x 7 x 5 x 1 x 1 x 109 = 22890

Least Common Multiple of 30,42,42,109 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 30,42,42,109 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,42,42,109) = 1

common factors(in case of two or more numbers have common factors) = 252

GCF(30,42,42,109) x common factors =1 x 252 = 252

LCM(30,42,42,109) = ( 30 × 42 × 42 × 109 ) / 252

LCM(30,42,42,109) = 5768280 / 252

LCM(30,42,42,109) = 22890

∴ Least Common Multiple of 30,42,42,109 is 22890
