Least Common Multiple of 56,78,78,40,842

Least Common Multiple (LCM) of 56,78,78,40,842 is 4597320

2 56, 78, 78, 40, 842
2 28, 39, 39, 20, 421
2 14, 39, 39, 10, 421
3 7, 39, 39, 5, 421
13 7, 13, 13, 5, 421
7, 1, 1, 5, 421

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 13 x 7 x 1 x 1 x 5 x 421 = 4597320

Least Common Multiple of 56,78,78,40,842 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 56,78,78,40,842 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,78,78,40,842) = 2

common factors(in case of two or more numbers have common factors) = 1248

GCF(56,78,78,40,842) x common factors =2 x 1248 = 2496

LCM(56,78,78,40,842) = ( 56 × 78 × 78 × 40 × 842 ) / 2496

LCM(56,78,78,40,842) = 11474910720 / 2496

LCM(56,78,78,40,842) = 4597320

∴ Least Common Multiple of 56,78,78,40,842 is 4597320
