Least Common Multiple of 728,1991

Least Common Multiple (LCM) of 728,1991 is 1449448

Given numbers has no common factors except 1. So, there LCM is their product i.e 1449448

Least Common Multiple of 728,1991 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 728,1991 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(728,1991) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(728,1991) x common factors =1 x 1 = 1

LCM(728,1991) = ( 728 × 1991 ) / 1

LCM(728,1991) = 1449448 / 1

LCM(728,1991) = 1449448

∴ Least Common Multiple of 728,1991 is 1449448
