LCM of:

Least Common Multiple of 686/81,122/1223

Given numbers are 686/81,122/1223

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 686,122

Least Common Multiple of Numerators i.e. LCM of 686,122 is 41846.

GCF of Denominators means GCF of 81,1223 as per the given fractions.

GCF of 81,1223 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 686,122

LCM of Fractions 686/81,122/1223 is 41846

2 686, 122
343, 61

∴ So the LCM of the given numbers is 2 x 343 x 61 = 41846

Least Common Multiple of 686,122 with GCF Formula

Least Common Multiple of 686,122 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 686,122 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(686,122) = 2

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

GCF(686,122) x common factors =2 x 1 = 2

LCM(686,122) = ( 686 × 122 ) / 2

LCM(686,122) = 83692 / 2

LCM(686,122) = 41846


Lets's calculate GCF of 81,1223

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 41846/1

Therefore the LCM of Fractions 686/81,122/1223 is 41846
