LCM of:

Least Common Multiple of 30,42,72,228

Least Common Multiple (LCM) of 30,42,72,228 is 47880

2 30, 42, 72, 228
2 15, 21, 36, 114
3 15, 21, 18, 57
5, 7, 6, 19

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 x 6 x 19 = 47880

Least Common Multiple of 30,42,72,228 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 30,42,72,228 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(30,42,72,228) = 6

common factors(in case of two or more numbers have common factors) = 72

GCF(30,42,72,228) x common factors =6 x 72 = 432

LCM(30,42,72,228) = ( 30 × 42 × 72 × 228 ) / 432

LCM(30,42,72,228) = 20684160 / 432

LCM(30,42,72,228) = 47880

∴ Least Common Multiple of 30,42,72,228 is 47880
