LCM of:

Least Common Multiple of 43,30,84,644

Least Common Multiple (LCM) of 43,30,84,644 is 415380

2 43, 30, 84, 644
2 43, 15, 42, 322
3 43, 15, 21, 161
7 43, 5, 7, 161
43, 5, 1, 23

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 43 x 5 x 1 x 23 = 415380

Least Common Multiple of 43,30,84,644 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 43,30,84,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(43,30,84,644) = 1

common factors(in case of two or more numbers have common factors) = 168

GCF(43,30,84,644) x common factors =1 x 168 = 168

LCM(43,30,84,644) = ( 43 × 30 × 84 × 644 ) / 168

LCM(43,30,84,644) = 69783840 / 168

LCM(43,30,84,644) = 415380

∴ Least Common Multiple of 43,30,84,644 is 415380
