LCM of:

Least Common Multiple of 78,30,45,891

Least Common Multiple (LCM) of 78,30,45,891 is 115830

2 78, 30, 45, 891
3 39, 15, 45, 891
3 13, 5, 15, 297
5 13, 5, 5, 99
13, 1, 1, 99

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 13 x 1 x 1 x 99 = 115830

Least Common Multiple of 78,30,45,891 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 78,30,45,891 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,30,45,891) = 3

common factors(in case of two or more numbers have common factors) = 270

GCF(78,30,45,891) x common factors =3 x 270 = 810

LCM(78,30,45,891) = ( 78 × 30 × 45 × 891 ) / 810

LCM(78,30,45,891) = 93822300 / 810

LCM(78,30,45,891) = 115830

∴ Least Common Multiple of 78,30,45,891 is 115830
