Least Common Multiple (LCM) of 66/38, 13/64 is 429.

LCM(66/38, 13/64) = 429

LCM of 66/38, 13/64

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 66/38,13/64

Given numbers are 66/38,13/64

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 66,13

Least Common Multiple of Numerators i.e. LCM of 66,13 is 858.

GCF of Denominators means GCF of 38,64 as per the given fractions.

GCF of 38,64 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 66,13

LCM of Fractions 66/38,13/64 is 429

Given numbers has no common factors except 1. So, there LCM is their product i.e 858

Least Common Multiple of 66,13 with GCF Formula

Least Common Multiple of 66,13 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 66,13 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,13) = 1

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

GCF(66,13) x common factors =1 x 1 = 1

LCM(66,13) = ( 66 × 13 ) / 1

LCM(66,13) = 858 / 1

LCM(66,13) = 858


Lets's calculate GCF of 38,64

2 38, 64
19, 32

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 858/2

Therefore the LCM of Fractions 66/38,13/64 is 429
