LCM of:

Least Common Multiple of 21/755,28/364,398/442

Given numbers are 21/755,28/364,398/442

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 21,28,398

Least Common Multiple of Numerators i.e. LCM of 21,28,398 is 16716.

GCF of Denominators means GCF of 755,364,442 as per the given fractions.

GCF of 755,364,442 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,28,398

LCM of Fractions 21/755,28/364,398/442 is 16716

2 21, 28, 398
7 21, 14, 199
3, 2, 199

∴ So the LCM of the given numbers is 2 x 7 x 3 x 2 x 199 = 16716

Least Common Multiple of 21,28,398 with GCF Formula

Least Common Multiple of 21,28,398 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 21,28,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,28,398) = 1

common factors(in case of two or more numbers have common factors) = 14

GCF(21,28,398) x common factors =1 x 14 = 14

LCM(21,28,398) = ( 21 × 28 × 398 ) / 14

LCM(21,28,398) = 234024 / 14

LCM(21,28,398) = 16716


Lets's calculate GCF of 755,364,442

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 16716/1

Therefore the LCM of Fractions 21/755,28/364,398/442 is 16716
