Least Common Multiple of 86/15,86/81,39/92,51/399

Given numbers are 86/15,86/81,39/92,51/399

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 86,86,39,51

Least Common Multiple of Numerators i.e. LCM of 86,86,39,51 is 57018.

GCF of Denominators means GCF of 15,81,92,399 as per the given fractions.

GCF of 15,81,92,399 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 86,86,39,51

LCM of Fractions 86/15,86/81,39/92,51/399 is 57018

2 86, 86, 39, 51
3 43, 43, 39, 51
43 43, 43, 13, 17
1, 1, 13, 17

∴ So the LCM of the given numbers is 2 x 3 x 43 x 1 x 1 x 13 x 17 = 57018

Least Common Multiple of 86,86,39,51 with GCF Formula

Least Common Multiple of 86,86,39,51 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 86,86,39,51 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(86,86,39,51) = 1

common factors(in case of two or more numbers have common factors) = 258

GCF(86,86,39,51) x common factors =1 x 258 = 258

LCM(86,86,39,51) = ( 86 × 86 × 39 × 51 ) / 258

LCM(86,86,39,51) = 14710644 / 258

LCM(86,86,39,51) = 57018


Lets's calculate GCF of 15,81,92,399

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 57018/1

Therefore the LCM of Fractions 86/15,86/81,39/92,51/399 is 57018
