Least Common Multiple of 72/429,68/846,132/921

Given numbers are 72/429,68/846,132/921

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 72,68,132

Least Common Multiple of Numerators i.e. LCM of 72,68,132 is 13464.

GCF of Denominators means GCF of 429,846,921 as per the given fractions.

GCF of 429,846,921 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 72,68,132

LCM of Fractions 72/429,68/846,132/921 is 4488

2 72, 68, 132
2 36, 34, 66
3 18, 17, 33
6, 17, 11

∴ So the LCM of the given numbers is 2 x 2 x 3 x 6 x 17 x 11 = 13464

Least Common Multiple of 72,68,132 with GCF Formula

Least Common Multiple of 72,68,132 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 72,68,132 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,68,132) = 4

common factors(in case of two or more numbers have common factors) = 12

GCF(72,68,132) x common factors =4 x 12 = 48

LCM(72,68,132) = ( 72 × 68 × 132 ) / 48

LCM(72,68,132) = 646272 / 48

LCM(72,68,132) = 13464


Lets's calculate GCF of 429,846,921

3 429, 846, 921
143, 282, 307

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 13464/3

Therefore the LCM of Fractions 72/429,68/846,132/921 is 4488
