Least Common Multiple of 69/51,69/42,10/23,12/921

Given numbers are 69/51,69/42,10/23,12/921

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 69,69,10,12

Least Common Multiple of Numerators i.e. LCM of 69,69,10,12 is 1380.

GCF of Denominators means GCF of 51,42,23,921 as per the given fractions.

GCF of 51,42,23,921 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 69,69,10,12

LCM of Fractions 69/51,69/42,10/23,12/921 is 1380

2 69, 69, 10, 12
3 69, 69, 5, 6
23 23, 23, 5, 2
1, 1, 5, 2

∴ So the LCM of the given numbers is 2 x 3 x 23 x 1 x 1 x 5 x 2 = 1380

Least Common Multiple of 69,69,10,12 with GCF Formula

Least Common Multiple of 69,69,10,12 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 69,69,10,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,69,10,12) = 1

common factors(in case of two or more numbers have common factors) = 414

GCF(69,69,10,12) x common factors =1 x 414 = 414

LCM(69,69,10,12) = ( 69 × 69 × 10 × 12 ) / 414

LCM(69,69,10,12) = 571320 / 414

LCM(69,69,10,12) = 1380


Lets's calculate GCF of 51,42,23,921

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1380/1

Therefore the LCM of Fractions 69/51,69/42,10/23,12/921 is 1380
