Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 71/72,70/12,47/55,72/79

Given numbers are 71/72,70/12,47/55,72/79

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 71,70,47,72

Least Common Multiple of Numerators i.e. LCM of 71,70,47,72 is 8409240.

GCF of Denominators means GCF of 72,12,55,79 as per the given fractions.

GCF of 72,12,55,79 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 71,70,47,72

LCM of Fractions 71/72,70/12,47/55,72/79 is 8409240

2 71, 70, 47, 72
71, 35, 47, 36

∴ So the LCM of the given numbers is 2 x 71 x 35 x 47 x 36 = 8409240

Least Common Multiple of 71,70,47,72 with GCF Formula

Least Common Multiple of 71,70,47,72 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 71,70,47,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,70,47,72) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(71,70,47,72) x common factors =1 x 2 = 2

LCM(71,70,47,72) = ( 71 × 70 × 47 × 72 ) / 2

LCM(71,70,47,72) = 16818480 / 2

LCM(71,70,47,72) = 8409240


Lets's calculate GCF of 72,12,55,79

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8409240/1

Therefore the LCM of Fractions 71/72,70/12,47/55,72/79 is 8409240
