Least Common Multiple of 42/61,11/22,63/68,12/717

Given numbers are 42/61,11/22,63/68,12/717

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 42,11,63,12

Least Common Multiple of Numerators i.e. LCM of 42,11,63,12 is 2772.

GCF of Denominators means GCF of 61,22,68,717 as per the given fractions.

GCF of 61,22,68,717 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,11,63,12

LCM of Fractions 42/61,11/22,63/68,12/717 is 2772

2 42, 11, 63, 12
3 21, 11, 63, 6
7 7, 11, 21, 2
1, 11, 3, 2

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 11 x 3 x 2 = 2772

Least Common Multiple of 42,11,63,12 with GCF Formula

Least Common Multiple of 42,11,63,12 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 42,11,63,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,11,63,12) = 1

common factors(in case of two or more numbers have common factors) = 126

GCF(42,11,63,12) x common factors =1 x 126 = 126

LCM(42,11,63,12) = ( 42 × 11 × 63 × 12 ) / 126

LCM(42,11,63,12) = 349272 / 126

LCM(42,11,63,12) = 2772


Lets's calculate GCF of 61,22,68,717

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2772/1

Therefore the LCM of Fractions 42/61,11/22,63/68,12/717 is 2772
