Least Common Multiple of 87/64,394/69,690/900

Given numbers are 87/64,394/69,690/900

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 87,394,690

Least Common Multiple of Numerators i.e. LCM of 87,394,690 is 3941970.

GCF of Denominators means GCF of 64,69,900 as per the given fractions.

GCF of 64,69,900 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 87,394,690

LCM of Fractions 87/64,394/69,690/900 is 3941970

2 87, 394, 690
3 87, 197, 345
29, 197, 115

∴ So the LCM of the given numbers is 2 x 3 x 29 x 197 x 115 = 3941970

Least Common Multiple of 87,394,690 with GCF Formula

Least Common Multiple of 87,394,690 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 87,394,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,394,690) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(87,394,690) x common factors =1 x 6 = 6

LCM(87,394,690) = ( 87 × 394 × 690 ) / 6

LCM(87,394,690) = 23651820 / 6

LCM(87,394,690) = 3941970


Lets's calculate GCF of 64,69,900

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3941970/1

Therefore the LCM of Fractions 87/64,394/69,690/900 is 3941970
