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 831/100,2021/686

Given numbers are 831/100,2021/686

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 831,2021

Least Common Multiple of Numerators i.e. LCM of 831,2021 is 1679451.

GCF of Denominators means GCF of 100,686 as per the given fractions.

GCF of 100,686 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 831,2021

LCM of Fractions 831/100,2021/686 is 1679451/2

Given numbers has no common factors except 1. So, there LCM is their product i.e 1679451

Least Common Multiple of 831,2021 with GCF Formula

Least Common Multiple of 831,2021 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 831,2021 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(831,2021) = 1

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

GCF(831,2021) x common factors =1 x 1 = 1

LCM(831,2021) = ( 831 × 2021 ) / 1

LCM(831,2021) = 1679451 / 1

LCM(831,2021) = 1679451


Lets's calculate GCF of 100,686

2 100, 686
50, 343

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1679451/2

Therefore the LCM of Fractions 831/100,2021/686 is 1679451/2
