Least Common Multiple of 56/63,90/91,831/847

Given numbers are 56/63,90/91,831/847

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 56,90,831

Least Common Multiple of Numerators i.e. LCM of 56,90,831 is 698040.

GCF of Denominators means GCF of 63,91,847 as per the given fractions.

GCF of 63,91,847 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 56,90,831

LCM of Fractions 56/63,90/91,831/847 is 99720

2 56, 90, 831
3 28, 45, 831
28, 15, 277

∴ So the LCM of the given numbers is 2 x 3 x 28 x 15 x 277 = 698040

Least Common Multiple of 56,90,831 with GCF Formula

Least Common Multiple of 56,90,831 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 56,90,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,90,831) = 1

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

GCF(56,90,831) x common factors =1 x 6 = 6

LCM(56,90,831) = ( 56 × 90 × 831 ) / 6

LCM(56,90,831) = 4188240 / 6

LCM(56,90,831) = 698040


Lets's calculate GCF of 63,91,847

7 63, 91, 847
9, 13, 121

∴ So the GCF of the given numbers is 7 = 7

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 698040/7

Therefore the LCM of Fractions 56/63,90/91,831/847 is 99720
