Least Common Multiple of 10/45,80/47,67/89,31/394

Given numbers are 10/45,80/47,67/89,31/394

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 10,80,67,31

Least Common Multiple of Numerators i.e. LCM of 10,80,67,31 is 166160.

GCF of Denominators means GCF of 45,47,89,394 as per the given fractions.

GCF of 45,47,89,394 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 10,80,67,31

LCM of Fractions 10/45,80/47,67/89,31/394 is 166160

2 10, 80, 67, 31
5 5, 40, 67, 31
1, 8, 67, 31

∴ So the LCM of the given numbers is 2 x 5 x 1 x 8 x 67 x 31 = 166160

Least Common Multiple of 10,80,67,31 with GCF Formula

Least Common Multiple of 10,80,67,31 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 10,80,67,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(10,80,67,31) = 1

common factors(in case of two or more numbers have common factors) = 10

GCF(10,80,67,31) x common factors =1 x 10 = 10

LCM(10,80,67,31) = ( 10 × 80 × 67 × 31 ) / 10

LCM(10,80,67,31) = 1661600 / 10

LCM(10,80,67,31) = 166160


Lets's calculate GCF of 45,47,89,394

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 166160/1

Therefore the LCM of Fractions 10/45,80/47,67/89,31/394 is 166160
