Least Common Multiple of 798/81,198/78,155/85

Given numbers are 798/81,198/78,155/85

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 798,198,155

Least Common Multiple of Numerators i.e. LCM of 798,198,155 is 4081770.

GCF of Denominators means GCF of 81,78,85 as per the given fractions.

GCF of 81,78,85 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 798,198,155

LCM of Fractions 798/81,198/78,155/85 is 4081770

2 798, 198, 155
3 399, 99, 155
133, 33, 155

∴ So the LCM of the given numbers is 2 x 3 x 133 x 33 x 155 = 4081770

Least Common Multiple of 798,198,155 with GCF Formula

Least Common Multiple of 798,198,155 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 798,198,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(798,198,155) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(798,198,155) x common factors =1 x 6 = 6

LCM(798,198,155) = ( 798 × 198 × 155 ) / 6

LCM(798,198,155) = 24490620 / 6

LCM(798,198,155) = 4081770


Lets's calculate GCF of 81,78,85

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4081770/1

Therefore the LCM of Fractions 798/81,198/78,155/85 is 4081770
