Least Common Multiple of 78/68,505/23,451/990

Given numbers are 78/68,505/23,451/990

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 78,505,451

Least Common Multiple of Numerators i.e. LCM of 78,505,451 is 17764890.

GCF of Denominators means GCF of 68,23,990 as per the given fractions.

GCF of 68,23,990 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,505,451

LCM of Fractions 78/68,505/23,451/990 is 17764890

Given numbers has no common factors except 1. So, there LCM is their product i.e 17764890

Least Common Multiple of 78,505,451 with GCF Formula

Least Common Multiple of 78,505,451 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 78,505,451 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,505,451) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(78,505,451) x common factors =1 x 1 = 1

LCM(78,505,451) = ( 78 × 505 × 451 ) / 1

LCM(78,505,451) = 17764890 / 1

LCM(78,505,451) = 17764890


Lets's calculate GCF of 68,23,990

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 17764890/1

Therefore the LCM of Fractions 78/68,505/23,451/990 is 17764890
