GCF of Denominators means GCF of 40,64,442 as per the given fractions.

GCF of 40,64,442 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 124,409,787

LCM of Fractions 124/40,409/64,787/442 is 19956746

Given numbers has no common factors except 1. So, there LCM is their product i.e 39913492

Least Common Multiple of 124,409,787 with GCF Formula

Least Common Multiple of 124,409,787 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 124,409,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(124,409,787) = 1

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

GCF(124,409,787) x common factors =1 x 1 = 1

LCM(124,409,787) = ( 124 × 409 × 787 ) / 1

LCM(124,409,787) = 39913492 / 1

LCM(124,409,787) = 39913492


Lets's calculate GCF of 40,64,442

2 40, 64, 442
20, 32, 221

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 39913492/2

Therefore the LCM of Fractions 124/40,409/64,787/442 is 19956746
