LCM of:

Least Common Multiple of 93/81,42/36,49/57

Given numbers are 93/81,42/36,49/57

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 93,42,49

Least Common Multiple of Numerators i.e. LCM of 93,42,49 is 9114.

GCF of Denominators means GCF of 81,36,57 as per the given fractions.

GCF of 81,36,57 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 93,42,49

LCM of Fractions 93/81,42/36,49/57 is 3038

3 93, 42, 49
7 31, 14, 49
31, 2, 7

∴ So the LCM of the given numbers is 3 x 7 x 31 x 2 x 7 = 9114

Least Common Multiple of 93,42,49 with GCF Formula

Least Common Multiple of 93,42,49 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 93,42,49 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(93,42,49) = 1

common factors(in case of two or more numbers have common factors) = 21

GCF(93,42,49) x common factors =1 x 21 = 21

LCM(93,42,49) = ( 93 × 42 × 49 ) / 21

LCM(93,42,49) = 191394 / 21

LCM(93,42,49) = 9114


Lets's calculate GCF of 81,36,57

3 81, 36, 57
27, 12, 19

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9114/3

Therefore the LCM of Fractions 93/81,42/36,49/57 is 3038
