Least Common Multiple of 120/23,560/21,235/19

Given numbers are 120/23,560/21,235/19

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 120,560,235

Least Common Multiple of Numerators i.e. LCM of 120,560,235 is 78960.

GCF of Denominators means GCF of 23,21,19 as per the given fractions.

GCF of 23,21,19 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 120,560,235

LCM of Fractions 120/23,560/21,235/19 is 78960

2 120, 560, 235
2 60, 280, 235
2 30, 140, 235
5 15, 70, 235
3, 14, 47

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 3 x 14 x 47 = 78960

Least Common Multiple of 120,560,235 with GCF Formula

Least Common Multiple of 120,560,235 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 120,560,235 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(120,560,235) = 5

common factors(in case of two or more numbers have common factors) = 40

GCF(120,560,235) x common factors =5 x 40 = 200

LCM(120,560,235) = ( 120 × 560 × 235 ) / 200

LCM(120,560,235) = 15792000 / 200

LCM(120,560,235) = 78960


Lets's calculate GCF of 23,21,19

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 78960/1

Therefore the LCM of Fractions 120/23,560/21,235/19 is 78960
