Least Common Multiple of 64/49,86/28,122/56

Given numbers are 64/49,86/28,122/56

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 64,86,122

Least Common Multiple of Numerators i.e. LCM of 64,86,122 is 167872.

GCF of Denominators means GCF of 49,28,56 as per the given fractions.

GCF of 49,28,56 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 64,86,122

LCM of Fractions 64/49,86/28,122/56 is 167872/7

2 64, 86, 122
32, 43, 61

∴ So the LCM of the given numbers is 2 x 32 x 43 x 61 = 167872

Least Common Multiple of 64,86,122 with GCF Formula

Least Common Multiple of 64,86,122 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 64,86,122 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(64,86,122) = 2

common factors(in case of two or more numbers have common factors) = 2

GCF(64,86,122) x common factors =2 x 2 = 4

LCM(64,86,122) = ( 64 × 86 × 122 ) / 4

LCM(64,86,122) = 671488 / 4

LCM(64,86,122) = 167872


Lets's calculate GCF of 49,28,56

7 49, 28, 56
7, 4, 8

∴ So the GCF of the given numbers is 7 = 7

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 167872/7

Therefore the LCM of Fractions 64/49,86/28,122/56 is 167872/7
