Least Common Multiple of 13/20,65/79,671/845

Given numbers are 13/20,65/79,671/845

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 13,65,671

Least Common Multiple of Numerators i.e. LCM of 13,65,671 is 43615.

GCF of Denominators means GCF of 20,79,845 as per the given fractions.

GCF of 20,79,845 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,65,671

LCM of Fractions 13/20,65/79,671/845 is 43615

13 13, 65, 671
1, 5, 671

∴ So the LCM of the given numbers is 13 x 1 x 5 x 671 = 43615

Least Common Multiple of 13,65,671 with GCF Formula

Least Common Multiple of 13,65,671 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 13,65,671 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,65,671) = 1

common factors(in case of two or more numbers have common factors) = 13

GCF(13,65,671) x common factors =1 x 13 = 13

LCM(13,65,671) = ( 13 × 65 × 671 ) / 13

LCM(13,65,671) = 566995 / 13

LCM(13,65,671) = 43615


Lets's calculate GCF of 20,79,845

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 43615/1

Therefore the LCM of Fractions 13/20,65/79,671/845 is 43615
