LCM of:

Least Common Multiple of 84,42,22,87,720

Least Common Multiple (LCM) of 84,42,22,87,720 is 1607760

2 84, 42, 22, 87, 720
2 42, 21, 11, 87, 360
3 21, 21, 11, 87, 180
7 7, 7, 11, 29, 60
1, 1, 11, 29, 60

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 1 x 1 x 11 x 29 x 60 = 1607760

Least Common Multiple of 84,42,22,87,720 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 84,42,22,87,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,42,22,87,720) = 1

common factors(in case of two or more numbers have common factors) = 3024

GCF(84,42,22,87,720) x common factors =1 x 3024 = 3024

LCM(84,42,22,87,720) = ( 84 × 42 × 22 × 87 × 720 ) / 3024

LCM(84,42,22,87,720) = 4861866240 / 3024

LCM(84,42,22,87,720) = 1607760

∴ Least Common Multiple of 84,42,22,87,720 is 1607760
