Least Common Multiple of 81/40,775/16,788/252

Given numbers are 81/40,775/16,788/252

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 81,775,788

Least Common Multiple of Numerators i.e. LCM of 81,775,788 is 49466700.

GCF of Denominators means GCF of 40,16,252 as per the given fractions.

GCF of 40,16,252 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,775,788

LCM of Fractions 81/40,775/16,788/252 is 12366675

Given numbers has no common factors except 1. So, there LCM is their product i.e 49466700

Least Common Multiple of 81,775,788 with GCF Formula

Least Common Multiple of 81,775,788 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 81,775,788 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,775,788) = 1

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

GCF(81,775,788) x common factors =1 x 1 = 1

LCM(81,775,788) = ( 81 × 775 × 788 ) / 1

LCM(81,775,788) = 49466700 / 1

LCM(81,775,788) = 49466700


Lets's calculate GCF of 40,16,252

2 40, 16, 252
2 20, 8, 126
10, 4, 63

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 49466700/4

Therefore the LCM of Fractions 81/40,775/16,788/252 is 12366675
