Least common multiple (LCM) of 40, 19, 80, 408 is 77520.

LCM(40, 19, 80, 408) = 77520

LCM of 40, 19, 80, 408

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 40,19,80,408

Least Common Multiple (LCM) of 40,19,80,408 is 77520

2 40, 19, 80, 408
2 20, 19, 40, 204
2 10, 19, 20, 102
5 5, 19, 10, 51
1, 19, 2, 51

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 19 x 2 x 51 = 77520

Least Common Multiple of 40,19,80,408 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 40,19,80,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,19,80,408) = 1

common factors(in case of two or more numbers have common factors) = 320

GCF(40,19,80,408) x common factors =1 x 320 = 320

LCM(40,19,80,408) = ( 40 × 19 × 80 × 408 ) / 320

LCM(40,19,80,408) = 24806400 / 320

LCM(40,19,80,408) = 77520

∴ Least Common Multiple of 40,19,80,408 is 77520
