LCM of:

Least Common Multiple of 16/42,78/63,92/243

Given numbers are 16/42,78/63,92/243

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 16,78,92

Least Common Multiple of Numerators i.e. LCM of 16,78,92 is 14352.

GCF of Denominators means GCF of 42,63,243 as per the given fractions.

GCF of 42,63,243 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 16,78,92

LCM of Fractions 16/42,78/63,92/243 is 4784

2 16, 78, 92
2 8, 39, 46
4, 39, 23

∴ So the LCM of the given numbers is 2 x 2 x 4 x 39 x 23 = 14352

Least Common Multiple of 16,78,92 with GCF Formula

Least Common Multiple of 16,78,92 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 16,78,92 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(16,78,92) = 2

common factors(in case of two or more numbers have common factors) = 4

GCF(16,78,92) x common factors =2 x 4 = 8

LCM(16,78,92) = ( 16 × 78 × 92 ) / 8

LCM(16,78,92) = 114816 / 8

LCM(16,78,92) = 14352


Lets's calculate GCF of 42,63,243

3 42, 63, 243
14, 21, 81

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 14352/3

Therefore the LCM of Fractions 16/42,78/63,92/243 is 4784
