LCM of:

Least Common Multiple of 449/21,308/1285

Given numbers are 449/21,308/1285

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 449,308

Least Common Multiple of Numerators i.e. LCM of 449,308 is 138292.

GCF of Denominators means GCF of 21,1285 as per the given fractions.

GCF of 21,1285 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 449,308

LCM of Fractions 449/21,308/1285 is 138292

Given numbers has no common factors except 1. So, there LCM is their product i.e 138292

Least Common Multiple of 449,308 with GCF Formula

Least Common Multiple of 449,308 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 449,308 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(449,308) = 1

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

GCF(449,308) x common factors =1 x 1 = 1

LCM(449,308) = ( 449 × 308 ) / 1

LCM(449,308) = 138292 / 1

LCM(449,308) = 138292


Lets's calculate GCF of 21,1285

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 138292/1

Therefore the LCM of Fractions 449/21,308/1285 is 138292
