LCM of:

Least Common Multiple of 21/398,7388/9924

Given numbers are 21/398,7388/9924

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 21,7388

Least Common Multiple of Numerators i.e. LCM of 21,7388 is 155148.

GCF of Denominators means GCF of 398,9924 as per the given fractions.

GCF of 398,9924 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,7388

LCM of Fractions 21/398,7388/9924 is 77574

Given numbers has no common factors except 1. So, there LCM is their product i.e 155148

Least Common Multiple of 21,7388 with GCF Formula

Least Common Multiple of 21,7388 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 21,7388 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,7388) = 1

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

GCF(21,7388) x common factors =1 x 1 = 1

LCM(21,7388) = ( 21 × 7388 ) / 1

LCM(21,7388) = 155148 / 1

LCM(21,7388) = 155148


Lets's calculate GCF of 398,9924

2 398, 9924
199, 4962

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 155148/2

Therefore the LCM of Fractions 21/398,7388/9924 is 77574
