LCM of:

Least Common Multiple of 68,19,40,420

Least Common Multiple (LCM) of 68,19,40,420 is 271320

2 68, 19, 40, 420
2 34, 19, 20, 210
5 17, 19, 10, 105
17, 19, 2, 21

∴ So the LCM of the given numbers is 2 x 2 x 5 x 17 x 19 x 2 x 21 = 271320

Least Common Multiple of 68,19,40,420 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 68,19,40,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,19,40,420) = 1

common factors(in case of two or more numbers have common factors) = 80

GCF(68,19,40,420) x common factors =1 x 80 = 80

LCM(68,19,40,420) = ( 68 × 19 × 40 × 420 ) / 80

LCM(68,19,40,420) = 21705600 / 80

LCM(68,19,40,420) = 271320

∴ Least Common Multiple of 68,19,40,420 is 271320
