LCM of:

Least Common Multiple of 40/76,20/82,170/177

Given numbers are 40/76,20/82,170/177

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 40,20,170

Least Common Multiple of Numerators i.e. LCM of 40,20,170 is 680.

GCF of Denominators means GCF of 76,82,177 as per the given fractions.

GCF of 76,82,177 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 40,20,170

LCM of Fractions 40/76,20/82,170/177 is 680

2 40, 20, 170
2 20, 10, 85
5 5, 10, 85
1, 2, 17

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 2 x 17 = 680

Least Common Multiple of 40,20,170 with GCF Formula

Least Common Multiple of 40,20,170 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 40,20,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,20,170) = 10

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

GCF(40,20,170) x common factors =10 x 20 = 200

LCM(40,20,170) = ( 40 × 20 × 170 ) / 200

LCM(40,20,170) = 136000 / 200

LCM(40,20,170) = 680


Lets's calculate GCF of 76,82,177

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 680/1

Therefore the LCM of Fractions 40/76,20/82,170/177 is 680
