Least Common Multiple of 25/34,65/46,78/45,81/109

Given numbers are 25/34,65/46,78/45,81/109

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 25,65,78,81

Least Common Multiple of Numerators i.e. LCM of 25,65,78,81 is 52650.

GCF of Denominators means GCF of 34,46,45,109 as per the given fractions.

GCF of 34,46,45,109 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 25,65,78,81

LCM of Fractions 25/34,65/46,78/45,81/109 is 52650

3 25, 65, 78, 81
5 25, 65, 26, 27
13 5, 13, 26, 27
5, 1, 2, 27

∴ So the LCM of the given numbers is 3 x 5 x 13 x 5 x 1 x 2 x 27 = 52650

Least Common Multiple of 25,65,78,81 with GCF Formula

Least Common Multiple of 25,65,78,81 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 25,65,78,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(25,65,78,81) = 1

common factors(in case of two or more numbers have common factors) = 195

GCF(25,65,78,81) x common factors =1 x 195 = 195

LCM(25,65,78,81) = ( 25 × 65 × 78 × 81 ) / 195

LCM(25,65,78,81) = 10266750 / 195

LCM(25,65,78,81) = 52650


Lets's calculate GCF of 34,46,45,109

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 52650/1

Therefore the LCM of Fractions 25/34,65/46,78/45,81/109 is 52650
