GCF of Denominators means GCF of 621,7769 as per the given fractions.

GCF of 621,7769 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,7249

LCM of Fractions 42/621,7249/7769 is 304458

Given numbers has no common factors except 1. So, there LCM is their product i.e 304458

Least Common Multiple of 42,7249 with GCF Formula

Least Common Multiple of 42,7249 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 42,7249 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,7249) = 1

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

GCF(42,7249) x common factors =1 x 1 = 1

LCM(42,7249) = ( 42 × 7249 ) / 1

LCM(42,7249) = 304458 / 1

LCM(42,7249) = 304458


Lets's calculate GCF of 621,7769

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 304458/1

Therefore the LCM of Fractions 42/621,7249/7769 is 304458
