Least Common Multiple (LCM) of 5/61, 7/34, 7/18, 89/681 is 3115.

LCM(5/61, 7/34, 7/18, 89/681) = 3115

LCM of 5/61, 7/34, 7/18, 89/681

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 5/61,7/34,7/18,89/681

Given numbers are 5/61,7/34,7/18,89/681

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 5,7,7,89

Least Common Multiple of Numerators i.e. LCM of 5,7,7,89 is 3115.

GCF of Denominators means GCF of 61,34,18,681 as per the given fractions.

GCF of 61,34,18,681 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 5,7,7,89

LCM of Fractions 5/61,7/34,7/18,89/681 is 3115

7 5, 7, 7, 89
5, 1, 1, 89

∴ So the LCM of the given numbers is 7 x 5 x 1 x 1 x 89 = 3115

Least Common Multiple of 5,7,7,89 with GCF Formula

Least Common Multiple of 5,7,7,89 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 5,7,7,89 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(5,7,7,89) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(5,7,7,89) x common factors =1 x 7 = 7

LCM(5,7,7,89) = ( 5 × 7 × 7 × 89 ) / 7

LCM(5,7,7,89) = 21805 / 7

LCM(5,7,7,89) = 3115


Lets's calculate GCF of 61,34,18,681

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3115/1

Therefore the LCM of Fractions 5/61,7/34,7/18,89/681 is 3115
