LCM of 32/17, 31/31, 21/67

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 32/17,31/31,21/67

Given numbers are 32/17,31/31,21/67

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 32,31,21

Least Common Multiple of Numerators i.e. LCM of 32,31,21 is 20832.

GCF of Denominators means GCF of 17,31,67 as per the given fractions.

GCF of 17,31,67 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 32,31,21

LCM of Fractions 32/17,31/31,21/67 is 20832

Given numbers has no common factors except 1. So, there LCM is their product i.e 20832

Least Common Multiple of 32,31,21 with GCF Formula

Least Common Multiple of 32,31,21 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 32,31,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(32,31,21) = 1

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

GCF(32,31,21) x common factors =1 x 1 = 1

LCM(32,31,21) = ( 32 × 31 × 21 ) / 1

LCM(32,31,21) = 20832 / 1

LCM(32,31,21) = 20832


Lets's calculate GCF of 17,31,67

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 20832/1

Therefore the LCM of Fractions 32/17,31/31,21/67 is 20832
