Least Common Multiple of 392/80,7409/780

Given numbers are 392/80,7409/780

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 392,7409

Least Common Multiple of Numerators i.e. LCM of 392,7409 is 2904328.

GCF of Denominators means GCF of 80,780 as per the given fractions.

GCF of 80,780 is 20 as it is the largest common factor for these numbers.

Lets's calculate LCM of 392,7409

LCM of Fractions 392/80,7409/780 is 2904328/20

Given numbers has no common factors except 1. So, there LCM is their product i.e 2904328

Least Common Multiple of 392,7409 with GCF Formula

Least Common Multiple of 392,7409 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 392,7409 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(392,7409) = 1

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

GCF(392,7409) x common factors =1 x 1 = 1

LCM(392,7409) = ( 392 × 7409 ) / 1

LCM(392,7409) = 2904328 / 1

LCM(392,7409) = 2904328


Lets's calculate GCF of 80,780

2 80, 780
2 40, 390
5 20, 195
4, 39

∴ So the GCF of the given numbers is 2 x 2 x 5 = 20

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2904328/20

Therefore the LCM of Fractions 392/80,7409/780 is 2904328/20
