Least common multiple (LCM) of 81, 40, 87, 40 is 93960.

LCM(81, 40, 87, 40) = 93960

LCM of 81, 40, 87, 40

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

LCM of:

Least Common Multiple of 81,40,87,40

Least Common Multiple (LCM) of 81,40,87,40 is 93960

2 81, 40, 87, 40
2 81, 20, 87, 20
2 81, 10, 87, 10
3 81, 5, 87, 5
5 27, 5, 29, 5
27, 1, 29, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 27 x 1 x 29 x 1 = 93960

Least Common Multiple of 81,40,87,40 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 81,40,87,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,40,87,40) = 1

common factors(in case of two or more numbers have common factors) = 120

GCF(81,40,87,40) x common factors =1 x 120 = 120

LCM(81,40,87,40) = ( 81 × 40 × 87 × 40 ) / 120

LCM(81,40,87,40) = 11275200 / 120

LCM(81,40,87,40) = 93960

∴ Least Common Multiple of 81,40,87,40 is 93960
