LCM of:

Least Common Multiple of 29/38,78/45,71/18,61/86

Given numbers are 29/38,78/45,71/18,61/86

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 29,78,71,61

Least Common Multiple of Numerators i.e. LCM of 29,78,71,61 is 9796722.

GCF of Denominators means GCF of 38,45,18,86 as per the given fractions.

GCF of 38,45,18,86 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 29,78,71,61

LCM of Fractions 29/38,78/45,71/18,61/86 is 9796722

Given numbers has no common factors except 1. So, there LCM is their product i.e 9796722

Least Common Multiple of 29,78,71,61 with GCF Formula

Least Common Multiple of 29,78,71,61 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 29,78,71,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(29,78,71,61) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(29,78,71,61) x common factors =1 x 1 = 1

LCM(29,78,71,61) = ( 29 × 78 × 71 × 61 ) / 1

LCM(29,78,71,61) = 9796722 / 1

LCM(29,78,71,61) = 9796722


Lets's calculate GCF of 38,45,18,86

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9796722/1

Therefore the LCM of Fractions 29/38,78/45,71/18,61/86 is 9796722
