Least Common Multiple of 99/83,21/12,961/80

Given numbers are 99/83,21/12,961/80

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 99,21,961

Least Common Multiple of Numerators i.e. LCM of 99,21,961 is 665973.

GCF of Denominators means GCF of 83,12,80 as per the given fractions.

GCF of 83,12,80 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 99,21,961

LCM of Fractions 99/83,21/12,961/80 is 665973

3 99, 21, 961
33, 7, 961

∴ So the LCM of the given numbers is 3 x 33 x 7 x 961 = 665973

Least Common Multiple of 99,21,961 with GCF Formula

Least Common Multiple of 99,21,961 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 99,21,961 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(99,21,961) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(99,21,961) x common factors =1 x 3 = 3

LCM(99,21,961) = ( 99 × 21 × 961 ) / 3

LCM(99,21,961) = 1997919 / 3

LCM(99,21,961) = 665973


Lets's calculate GCF of 83,12,80

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 665973/1

Therefore the LCM of Fractions 99/83,21/12,961/80 is 665973
