LCM of:

Least Common Multiple of 78/904,39/143,106/989

Given numbers are 78/904,39/143,106/989

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 78,39,106

Least Common Multiple of Numerators i.e. LCM of 78,39,106 is 4134.

GCF of Denominators means GCF of 904,143,989 as per the given fractions.

GCF of 904,143,989 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,39,106

LCM of Fractions 78/904,39/143,106/989 is 4134

2 78, 39, 106
3 39, 39, 53
13 13, 13, 53
1, 1, 53

∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 1 x 53 = 4134

Least Common Multiple of 78,39,106 with GCF Formula

Least Common Multiple of 78,39,106 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 78,39,106 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,39,106) = 1

common factors(in case of two or more numbers have common factors) = 78

GCF(78,39,106) x common factors =1 x 78 = 78

LCM(78,39,106) = ( 78 × 39 × 106 ) / 78

LCM(78,39,106) = 322452 / 78

LCM(78,39,106) = 4134


Lets's calculate GCF of 904,143,989

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4134/1

Therefore the LCM of Fractions 78/904,39/143,106/989 is 4134
