Least Common Multiple of 389,20,406,638

Least Common Multiple (LCM) of 389,20,406,638 is 17372740

2	389, 20, 406, 638
29	389, 10, 203, 319
	389, 10, 7, 11

∴ So the LCM of the given numbers is 2 x 29 x 389 x 10 x 7 x 11 = 17372740

Least Common Multiple of 389,20,406,638 with GCF Formula

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 389,20,406,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(389,20,406,638) = 1

common factors(in case of two or more numbers have common factors) = 116

GCF(389,20,406,638) x common factors =1 x 116 = 116

LCM(389,20,406,638) = ( 389 × 20 × 406 × 638 ) / 116

LCM(389,20,406,638) = 2015237840 / 116

LCM(389,20,406,638) = 17372740

∴ Least Common Multiple of 389,20,406,638 is 17372740
