Least Common Multiple of 68/78,272/18,250/390

Given numbers are 68/78,272/18,250/390

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 68,272,250

Least Common Multiple of Numerators i.e. LCM of 68,272,250 is 34000.

GCF of Denominators means GCF of 78,18,390 as per the given fractions.

GCF of 78,18,390 is 6 as it is the largest common factor for these numbers.

Lets's calculate LCM of 68,272,250

LCM of Fractions 68/78,272/18,250/390 is 34000/6

2 68, 272, 250
2 34, 136, 125
17 17, 68, 125
1, 4, 125

∴ So the LCM of the given numbers is 2 x 2 x 17 x 1 x 4 x 125 = 34000

Least Common Multiple of 68,272,250 with GCF Formula

Least Common Multiple of 68,272,250 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 68,272,250 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,272,250) = 2

common factors(in case of two or more numbers have common factors) = 68

GCF(68,272,250) x common factors =2 x 68 = 136

LCM(68,272,250) = ( 68 × 272 × 250 ) / 136

LCM(68,272,250) = 4624000 / 136

LCM(68,272,250) = 34000


Lets's calculate GCF of 78,18,390

2 78, 18, 390
3 39, 9, 195
13, 3, 65

∴ So the GCF of the given numbers is 2 x 3 = 6

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 34000/6

Therefore the LCM of Fractions 68/78,272/18,250/390 is 34000/6
