Least Common Multiple of 82/12,87/18,68/39,36/309

Given numbers are 82/12,87/18,68/39,36/309

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 82,87,68,36

Least Common Multiple of Numerators i.e. LCM of 82,87,68,36 is 727668.

GCF of Denominators means GCF of 12,18,39,309 as per the given fractions.

GCF of 12,18,39,309 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 82,87,68,36

LCM of Fractions 82/12,87/18,68/39,36/309 is 242556

2 82, 87, 68, 36
2 41, 87, 34, 18
3 41, 87, 17, 9
41, 29, 17, 3

∴ So the LCM of the given numbers is 2 x 2 x 3 x 41 x 29 x 17 x 3 = 727668

Least Common Multiple of 82,87,68,36 with GCF Formula

Least Common Multiple of 82,87,68,36 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 82,87,68,36 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(82,87,68,36) = 1

common factors(in case of two or more numbers have common factors) = 24

GCF(82,87,68,36) x common factors =1 x 24 = 24

LCM(82,87,68,36) = ( 82 × 87 × 68 × 36 ) / 24

LCM(82,87,68,36) = 17464032 / 24

LCM(82,87,68,36) = 727668


Lets's calculate GCF of 12,18,39,309

3 12, 18, 39, 309
4, 6, 13, 103

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 727668/3

Therefore the LCM of Fractions 82/12,87/18,68/39,36/309 is 242556
