LCM(721/70, 900/3020) = 64890

LCM of 721/70, 900/3020

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 721/70,900/3020

Given numbers are 721/70,900/3020

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 721,900

Least Common Multiple of Numerators i.e. LCM of 721,900 is 648900.

GCF of Denominators means GCF of 70,3020 as per the given fractions.

GCF of 70,3020 is 10 as it is the largest common factor for these numbers.

Lets's calculate LCM of 721,900

LCM of Fractions 721/70,900/3020 is 64890

Given numbers has no common factors except 1. So, there LCM is their product i.e 648900

Least Common Multiple of 721,900 with GCF Formula

Least Common Multiple of 721,900 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 721,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(721,900) = 1

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

GCF(721,900) x common factors =1 x 1 = 1

LCM(721,900) = ( 721 × 900 ) / 1

LCM(721,900) = 648900 / 1

LCM(721,900) = 648900


Lets's calculate GCF of 70,3020

2 70, 3020
5 35, 1510
7, 302

∴ So the GCF of the given numbers is 2 x 5 = 10

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 648900/10

Therefore the LCM of Fractions 721/70,900/3020 is 64890
