Least Common Multiple of 77/781,7400/3945

Given numbers are 77/781,7400/3945

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 77,7400

Least Common Multiple of Numerators i.e. LCM of 77,7400 is 569800.

GCF of Denominators means GCF of 781,3945 as per the given fractions.

GCF of 781,3945 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 77,7400

LCM of Fractions 77/781,7400/3945 is 569800

Given numbers has no common factors except 1. So, there LCM is their product i.e 569800

Least Common Multiple of 77,7400 with GCF Formula

Least Common Multiple of 77,7400 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 77,7400 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,7400) = 1

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

GCF(77,7400) x common factors =1 x 1 = 1

LCM(77,7400) = ( 77 × 7400 ) / 1

LCM(77,7400) = 569800 / 1

LCM(77,7400) = 569800


Lets's calculate GCF of 781,3945

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 569800/1

Therefore the LCM of Fractions 77/781,7400/3945 is 569800
