Least Common Multiple of 638/76,494/41,130/689

Given numbers are 638/76,494/41,130/689

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 638,494,130

Least Common Multiple of Numerators i.e. LCM of 638,494,130 is 787930.

GCF of Denominators means GCF of 76,41,689 as per the given fractions.

GCF of 76,41,689 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 638,494,130

LCM of Fractions 638/76,494/41,130/689 is 787930

2 638, 494, 130
13 319, 247, 65
319, 19, 5

∴ So the LCM of the given numbers is 2 x 13 x 319 x 19 x 5 = 787930

Least Common Multiple of 638,494,130 with GCF Formula

Least Common Multiple of 638,494,130 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 638,494,130 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(638,494,130) = 2

common factors(in case of two or more numbers have common factors) = 26

GCF(638,494,130) x common factors =2 x 26 = 52

LCM(638,494,130) = ( 638 × 494 × 130 ) / 52

LCM(638,494,130) = 40972360 / 52

LCM(638,494,130) = 787930


Lets's calculate GCF of 76,41,689

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 787930/1

Therefore the LCM of Fractions 638/76,494/41,130/689 is 787930
