LCM of:

Least Common Multiple of 78/331,14/660,105/111

Given numbers are 78/331,14/660,105/111

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 78,14,105

Least Common Multiple of Numerators i.e. LCM of 78,14,105 is 2730.

GCF of Denominators means GCF of 331,660,111 as per the given fractions.

GCF of 331,660,111 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,14,105

LCM of Fractions 78/331,14/660,105/111 is 2730

2 78, 14, 105
3 39, 7, 105
7 13, 7, 35
13, 1, 5

∴ So the LCM of the given numbers is 2 x 3 x 7 x 13 x 1 x 5 = 2730

Least Common Multiple of 78,14,105 with GCF Formula

Least Common Multiple of 78,14,105 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 78,14,105 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,14,105) = 1

common factors(in case of two or more numbers have common factors) = 42

GCF(78,14,105) x common factors =1 x 42 = 42

LCM(78,14,105) = ( 78 × 14 × 105 ) / 42

LCM(78,14,105) = 114660 / 42

LCM(78,14,105) = 2730


Lets's calculate GCF of 331,660,111

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2730/1

Therefore the LCM of Fractions 78/331,14/660,105/111 is 2730
