LCM of:

Least Common Multiple (LCM) of 60,84,140 By Common Division

2 60, 84, 140
2 30, 42, 70
3 15, 21, 35
5 5, 7, 35
7 1, 7, 7
1, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 x 1 x 1 x 1 = 420

Least Common Multiple of 60,84,140 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 60,84,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(60,84,140) = 4

common factors(in case of two or more numbers have common factors) = 420

GCF(60,84,140) x common factors =4 x 420 = 1680

LCM(60,84,140) = ( 60 × 84 × 140 ) / 1680

LCM(60,84,140) = 705600 / 1680

LCM(60,84,140) = 420

∴ Least Common Multiple of 60,84,140 is 420
