Least Common Multiple of 18/11,12/56,84/22,843/55

Given numbers are 18/11,12/56,84/22,843/55

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 18,12,84,843

Least Common Multiple of Numerators i.e. LCM of 18,12,84,843 is 70812.

GCF of Denominators means GCF of 11,56,22,55 as per the given fractions.

GCF of 11,56,22,55 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 18,12,84,843

LCM of Fractions 18/11,12/56,84/22,843/55 is 70812

2 18, 12, 84, 843
2 9, 6, 42, 843
3 9, 3, 21, 843
1, 3, 7, 281

∴ So the LCM of the given numbers is 2 x 2 x 3 x 1 x 3 x 7 x 281 = 70812

Least Common Multiple of 18,12,84,843 with GCF Formula

Least Common Multiple of 18,12,84,843 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 18,12,84,843 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,12,84,843) = 3

common factors(in case of two or more numbers have common factors) = 72

GCF(18,12,84,843) x common factors =3 x 72 = 216

LCM(18,12,84,843) = ( 18 × 12 × 84 × 843 ) / 216

LCM(18,12,84,843) = 15295392 / 216

LCM(18,12,84,843) = 70812


Lets's calculate GCF of 11,56,22,55

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 70812/1

Therefore the LCM of Fractions 18/11,12/56,84/22,843/55 is 70812
