Least Common Multiple of 38/49,207/70,133/644

Given numbers are 38/49,207/70,133/644

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 38,207,133

Least Common Multiple of Numerators i.e. LCM of 38,207,133 is 55062.

GCF of Denominators means GCF of 49,70,644 as per the given fractions.

GCF of 49,70,644 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 38,207,133

LCM of Fractions 38/49,207/70,133/644 is 7866

19 38, 207, 133
2, 207, 7

∴ So the LCM of the given numbers is 19 x 2 x 207 x 7 = 55062

Least Common Multiple of 38,207,133 with GCF Formula

Least Common Multiple of 38,207,133 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 38,207,133 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(38,207,133) = 1

common factors(in case of two or more numbers have common factors) = 19

GCF(38,207,133) x common factors =1 x 19 = 19

LCM(38,207,133) = ( 38 × 207 × 133 ) / 19

LCM(38,207,133) = 1046178 / 19

LCM(38,207,133) = 55062


Lets's calculate GCF of 49,70,644

7 49, 70, 644
7, 10, 92

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 55062/7

Therefore the LCM of Fractions 38/49,207/70,133/644 is 7866
