Lets's calculate LCM of 2109,1945

LCM of Fractions 2109/791,1945/7639 is 4102005

Given numbers has no common factors except 1. So, there LCM is their product i.e 4102005

Least Common Multiple of 2109,1945 with GCF Formula

Least Common Multiple of 2109,1945 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 2109,1945 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(2109,1945) = 1

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

GCF(2109,1945) x common factors =1 x 1 = 1

LCM(2109,1945) = ( 2109 × 1945 ) / 1

LCM(2109,1945) = 4102005 / 1

LCM(2109,1945) = 4102005


Lets's calculate GCF of 791,7639

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4102005/1

Therefore the LCM of Fractions 2109/791,1945/7639 is 4102005
