Lets's calculate LCM of 639,1961

LCM of Fractions 639/961,1961/489 is 1253079

Given numbers has no common factors except 1. So, there LCM is their product i.e 1253079

Least Common Multiple of 639,1961 with GCF Formula

Least Common Multiple of 639,1961 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 639,1961 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(639,1961) = 1

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

GCF(639,1961) x common factors =1 x 1 = 1

LCM(639,1961) = ( 639 × 1961 ) / 1

LCM(639,1961) = 1253079 / 1

LCM(639,1961) = 1253079


Lets's calculate GCF of 961,489

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1253079/1

Therefore the LCM of Fractions 639/961,1961/489 is 1253079
