Least Common Multiple (LCM) of 721/4, 16/18 is 5768.

LCM(721/4, 16/18) = 5768

LCM of 721/4, 16/18

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 721/4,16/18

Given numbers are 721/4,16/18

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 721,16

Least Common Multiple of Numerators i.e. LCM of 721,16 is 11536.

GCF of Denominators means GCF of 4,18 as per the given fractions.

GCF of 4,18 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 721,16

LCM of Fractions 721/4,16/18 is 5768

Given numbers has no common factors except 1. So, there LCM is their product i.e 11536

Least Common Multiple of 721,16 with GCF Formula

Least Common Multiple of 721,16 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 721,16 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(721,16) = 1

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

GCF(721,16) x common factors =1 x 1 = 1

LCM(721,16) = ( 721 × 16 ) / 1

LCM(721,16) = 11536 / 1

LCM(721,16) = 11536


Lets's calculate GCF of 4,18

2 4, 18
2, 9

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11536/2

Therefore the LCM of Fractions 721/4,16/18 is 5768
