Least Common Multiple of 78/15,70/33,159/343

Given numbers are 78/15,70/33,159/343

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 78,70,159

Least Common Multiple of Numerators i.e. LCM of 78,70,159 is 144690.

GCF of Denominators means GCF of 15,33,343 as per the given fractions.

GCF of 15,33,343 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,70,159

LCM of Fractions 78/15,70/33,159/343 is 144690

2 78, 70, 159
3 39, 35, 159
13, 35, 53

∴ So the LCM of the given numbers is 2 x 3 x 13 x 35 x 53 = 144690

Least Common Multiple of 78,70,159 with GCF Formula

Least Common Multiple of 78,70,159 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 78,70,159 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,70,159) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(78,70,159) x common factors =1 x 6 = 6

LCM(78,70,159) = ( 78 × 70 × 159 ) / 6

LCM(78,70,159) = 868140 / 6

LCM(78,70,159) = 144690


Lets's calculate GCF of 15,33,343

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 144690/1

Therefore the LCM of Fractions 78/15,70/33,159/343 is 144690
