Least Common Multiple of 7/99,77/69,645/33

Given numbers are 7/99,77/69,645/33

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 7,77,645

Least Common Multiple of Numerators i.e. LCM of 7,77,645 is 49665.

GCF of Denominators means GCF of 99,69,33 as per the given fractions.

GCF of 99,69,33 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 7,77,645

LCM of Fractions 7/99,77/69,645/33 is 16555

7 7, 77, 645
1, 11, 645

∴ So the LCM of the given numbers is 7 x 1 x 11 x 645 = 49665

Least Common Multiple of 7,77,645 with GCF Formula

Least Common Multiple of 7,77,645 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 7,77,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7,77,645) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(7,77,645) x common factors =1 x 7 = 7

LCM(7,77,645) = ( 7 × 77 × 645 ) / 7

LCM(7,77,645) = 347655 / 7

LCM(7,77,645) = 49665


Lets's calculate GCF of 99,69,33

3 99, 69, 33
33, 23, 11

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 49665/3

Therefore the LCM of Fractions 7/99,77/69,645/33 is 16555
