LCM(23/424, 70/138) = 805

LCM of 23/424, 70/138

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 23/424,70/138

Given numbers are 23/424,70/138

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 23,70

Least Common Multiple of Numerators i.e. LCM of 23,70 is 1610.

GCF of Denominators means GCF of 424,138 as per the given fractions.

GCF of 424,138 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 23,70

LCM of Fractions 23/424,70/138 is 805

Given numbers has no common factors except 1. So, there LCM is their product i.e 1610

Least Common Multiple of 23,70 with GCF Formula

Least Common Multiple of 23,70 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 23,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,70) = 1

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

GCF(23,70) x common factors =1 x 1 = 1

LCM(23,70) = ( 23 × 70 ) / 1

LCM(23,70) = 1610 / 1

LCM(23,70) = 1610


Lets's calculate GCF of 424,138

2 424, 138
212, 69

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1610/2

Therefore the LCM of Fractions 23/424,70/138 is 805
