LCM(71/172, 31/770) = 2201/2

LCM of 71/172, 31/770

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 71/172,31/770

Given numbers are 71/172,31/770

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 71,31

Least Common Multiple of Numerators i.e. LCM of 71,31 is 2201.

GCF of Denominators means GCF of 172,770 as per the given fractions.

GCF of 172,770 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 71,31

LCM of Fractions 71/172,31/770 is 2201/2

Given numbers has no common factors except 1. So, there LCM is their product i.e 2201

Least Common Multiple of 71,31 with GCF Formula

Least Common Multiple of 71,31 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 71,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,31) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(71,31) x common factors =1 x 1 = 1

LCM(71,31) = ( 71 × 31 ) / 1

LCM(71,31) = 2201 / 1

LCM(71,31) = 2201


Lets's calculate GCF of 172,770

2 172, 770
86, 385

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2201/2

Therefore the LCM of Fractions 71/172,31/770 is 2201/2
