LCM(32, 80, 91, 390) = 43680

LCM of 32, 80, 91, 390

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

LCM of:

Least Common Multiple of 32,80,91,390

Least Common Multiple (LCM) of 32,80,91,390 is 43680

2 32, 80, 91, 390
2 16, 40, 91, 195
2 8, 20, 91, 195
2 4, 10, 91, 195
5 2, 5, 91, 195
13 2, 1, 91, 39
2, 1, 7, 3

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 13 x 2 x 1 x 7 x 3 = 43680

Least Common Multiple of 32,80,91,390 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 32,80,91,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(32,80,91,390) = 1

common factors(in case of two or more numbers have common factors) = 2080

GCF(32,80,91,390) x common factors =1 x 2080 = 2080

LCM(32,80,91,390) = ( 32 × 80 × 91 × 390 ) / 2080

LCM(32,80,91,390) = 90854400 / 2080

LCM(32,80,91,390) = 43680

∴ Least Common Multiple of 32,80,91,390 is 43680
