Least Common Multiple of 78/13,79/61,65/91,76/251

Given numbers are 78/13,79/61,65/91,76/251

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 78,79,65,76

Least Common Multiple of Numerators i.e. LCM of 78,79,65,76 is 1170780.

GCF of Denominators means GCF of 13,61,91,251 as per the given fractions.

GCF of 13,61,91,251 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,79,65,76

LCM of Fractions 78/13,79/61,65/91,76/251 is 1170780

2 78, 79, 65, 76
13 39, 79, 65, 38
3, 79, 5, 38

∴ So the LCM of the given numbers is 2 x 13 x 3 x 79 x 5 x 38 = 1170780

Least Common Multiple of 78,79,65,76 with GCF Formula

Least Common Multiple of 78,79,65,76 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 78,79,65,76 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,79,65,76) = 1

common factors(in case of two or more numbers have common factors) = 26

GCF(78,79,65,76) x common factors =1 x 26 = 26

LCM(78,79,65,76) = ( 78 × 79 × 65 × 76 ) / 26

LCM(78,79,65,76) = 30440280 / 26

LCM(78,79,65,76) = 1170780


Lets's calculate GCF of 13,61,91,251

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1170780/1

Therefore the LCM of Fractions 78/13,79/61,65/91,76/251 is 1170780
