LCM of:

Least Common Multiple of 20/309,45/260,668/399

Given numbers are 20/309,45/260,668/399

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 20,45,668

Least Common Multiple of Numerators i.e. LCM of 20,45,668 is 30060.

GCF of Denominators means GCF of 309,260,399 as per the given fractions.

GCF of 309,260,399 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 20,45,668

LCM of Fractions 20/309,45/260,668/399 is 30060

2 20, 45, 668
2 10, 45, 334
5 5, 45, 167
1, 9, 167

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 9 x 167 = 30060

Least Common Multiple of 20,45,668 with GCF Formula

Least Common Multiple of 20,45,668 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 20,45,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,45,668) = 1

common factors(in case of two or more numbers have common factors) = 20

GCF(20,45,668) x common factors =1 x 20 = 20

LCM(20,45,668) = ( 20 × 45 × 668 ) / 20

LCM(20,45,668) = 601200 / 20

LCM(20,45,668) = 30060


Lets's calculate GCF of 309,260,399

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 30060/1

Therefore the LCM of Fractions 20/309,45/260,668/399 is 30060
