Least Common Multiple (LCM) of 77/12, 31/65 is 2387.

LCM(77/12, 31/65) = 2387

LCM of 77/12, 31/65

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 77/12,31/65

Given numbers are 77/12,31/65

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 77,31

Least Common Multiple of Numerators i.e. LCM of 77,31 is 2387.

GCF of Denominators means GCF of 12,65 as per the given fractions.

GCF of 12,65 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 77,31

LCM of Fractions 77/12,31/65 is 2387

Given numbers has no common factors except 1. So, there LCM is their product i.e 2387

Least Common Multiple of 77,31 with GCF Formula

Least Common Multiple of 77,31 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 77,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,31) = 1

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

GCF(77,31) x common factors =1 x 1 = 1

LCM(77,31) = ( 77 × 31 ) / 1

LCM(77,31) = 2387 / 1

LCM(77,31) = 2387


Lets's calculate GCF of 12,65

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2387/1

Therefore the LCM of Fractions 77/12,31/65 is 2387
