LCM of 87, 74, 40, 87

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

LCM of:

Least Common Multiple of 87,74,40,87

Least Common Multiple (LCM) of 87,74,40,87 is 128760

2 87, 74, 40, 87
3 87, 37, 20, 87
29 29, 37, 20, 29
1, 37, 20, 1

∴ So the LCM of the given numbers is 2 x 3 x 29 x 1 x 37 x 20 x 1 = 128760

Least Common Multiple of 87,74,40,87 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 87,74,40,87 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,74,40,87) = 1

common factors(in case of two or more numbers have common factors) = 174

GCF(87,74,40,87) x common factors =1 x 174 = 174

LCM(87,74,40,87) = ( 87 × 74 × 40 × 87 ) / 174

LCM(87,74,40,87) = 22404240 / 174

LCM(87,74,40,87) = 128760

∴ Least Common Multiple of 87,74,40,87 is 128760
