Least Common Multiple of 15/91,30/49,36/18,305/60

Given numbers are 15/91,30/49,36/18,305/60

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 15,30,36,305

Least Common Multiple of Numerators i.e. LCM of 15,30,36,305 is 10980.

GCF of Denominators means GCF of 91,49,18,60 as per the given fractions.

GCF of 91,49,18,60 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 15,30,36,305

LCM of Fractions 15/91,30/49,36/18,305/60 is 10980

2 15, 30, 36, 305
3 15, 15, 18, 305
5 5, 5, 6, 305
1, 1, 6, 61

∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 1 x 6 x 61 = 10980

Least Common Multiple of 15,30,36,305 with GCF Formula

Least Common Multiple of 15,30,36,305 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 15,30,36,305 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,30,36,305) = 1

common factors(in case of two or more numbers have common factors) = 450

GCF(15,30,36,305) x common factors =1 x 450 = 450

LCM(15,30,36,305) = ( 15 × 30 × 36 × 305 ) / 450

LCM(15,30,36,305) = 4941000 / 450

LCM(15,30,36,305) = 10980


Lets's calculate GCF of 91,49,18,60

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 10980/1

Therefore the LCM of Fractions 15/91,30/49,36/18,305/60 is 10980
