LCM of:

Least Common Multiple of 69,75,90,644

Least Common Multiple (LCM) of 69,75,90,644 is 144900

2 69, 75, 90, 644
3 69, 75, 45, 322
5 23, 25, 15, 322
23 23, 5, 3, 322
1, 5, 3, 14

∴ So the LCM of the given numbers is 2 x 3 x 5 x 23 x 1 x 5 x 3 x 14 = 144900

Least Common Multiple of 69,75,90,644 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 69,75,90,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,75,90,644) = 1

common factors(in case of two or more numbers have common factors) = 2070

GCF(69,75,90,644) x common factors =1 x 2070 = 2070

LCM(69,75,90,644) = ( 69 × 75 × 90 × 644 ) / 2070

LCM(69,75,90,644) = 299943000 / 2070

LCM(69,75,90,644) = 144900

∴ Least Common Multiple of 69,75,90,644 is 144900
