Least Common Multiple of 33/11,72/21,155/731

Given numbers are 33/11,72/21,155/731

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 33,72,155

Least Common Multiple of Numerators i.e. LCM of 33,72,155 is 122760.

GCF of Denominators means GCF of 11,21,731 as per the given fractions.

GCF of 11,21,731 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 33,72,155

LCM of Fractions 33/11,72/21,155/731 is 122760

3 33, 72, 155
11, 24, 155

∴ So the LCM of the given numbers is 3 x 11 x 24 x 155 = 122760

Least Common Multiple of 33,72,155 with GCF Formula

Least Common Multiple of 33,72,155 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 33,72,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(33,72,155) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(33,72,155) x common factors =1 x 3 = 3

LCM(33,72,155) = ( 33 × 72 × 155 ) / 3

LCM(33,72,155) = 368280 / 3

LCM(33,72,155) = 122760


Lets's calculate GCF of 11,21,731

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 122760/1

Therefore the LCM of Fractions 33/11,72/21,155/731 is 122760
