LCM of:

Least Common Multiple of 92/68,48/81,84/20

Given numbers are 92/68,48/81,84/20

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 92,48,84

Least Common Multiple of Numerators i.e. LCM of 92,48,84 is 7728.

GCF of Denominators means GCF of 68,81,20 as per the given fractions.

GCF of 68,81,20 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 92,48,84

LCM of Fractions 92/68,48/81,84/20 is 7728

2 92, 48, 84
2 46, 24, 42
3 23, 12, 21
23, 4, 7

∴ So the LCM of the given numbers is 2 x 2 x 3 x 23 x 4 x 7 = 7728

Least Common Multiple of 92,48,84 with GCF Formula

Least Common Multiple of 92,48,84 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 92,48,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(92,48,84) = 4

common factors(in case of two or more numbers have common factors) = 12

GCF(92,48,84) x common factors =4 x 12 = 48

LCM(92,48,84) = ( 92 × 48 × 84 ) / 48

LCM(92,48,84) = 370944 / 48

LCM(92,48,84) = 7728


Lets's calculate GCF of 68,81,20

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7728/1

Therefore the LCM of Fractions 92/68,48/81,84/20 is 7728
