Least Common Multiple of 13/39,36/61,68/85,71/835

Given numbers are 13/39,36/61,68/85,71/835

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 13,36,68,71

Least Common Multiple of Numerators i.e. LCM of 13,36,68,71 is 564876.

GCF of Denominators means GCF of 39,61,85,835 as per the given fractions.

GCF of 39,61,85,835 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,36,68,71

LCM of Fractions 13/39,36/61,68/85,71/835 is 564876

2 13, 36, 68, 71
2 13, 18, 34, 71
13, 9, 17, 71

∴ So the LCM of the given numbers is 2 x 2 x 13 x 9 x 17 x 71 = 564876

Least Common Multiple of 13,36,68,71 with GCF Formula

Least Common Multiple of 13,36,68,71 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 13,36,68,71 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,36,68,71) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(13,36,68,71) x common factors =1 x 4 = 4

LCM(13,36,68,71) = ( 13 × 36 × 68 × 71 ) / 4

LCM(13,36,68,71) = 2259504 / 4

LCM(13,36,68,71) = 564876


Lets's calculate GCF of 39,61,85,835

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 564876/1

Therefore the LCM of Fractions 13/39,36/61,68/85,71/835 is 564876
