Least Common Multiple of 775/25,420/99,489/90

Given numbers are 775/25,420/99,489/90

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 775,420,489

Least Common Multiple of Numerators i.e. LCM of 775,420,489 is 10611300.

GCF of Denominators means GCF of 25,99,90 as per the given fractions.

GCF of 25,99,90 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 775,420,489

LCM of Fractions 775/25,420/99,489/90 is 10611300

3 775, 420, 489
5 775, 140, 163
155, 28, 163

∴ So the LCM of the given numbers is 3 x 5 x 155 x 28 x 163 = 10611300

Least Common Multiple of 775,420,489 with GCF Formula

Least Common Multiple of 775,420,489 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 775,420,489 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(775,420,489) = 1

common factors(in case of two or more numbers have common factors) = 15

GCF(775,420,489) x common factors =1 x 15 = 15

LCM(775,420,489) = ( 775 × 420 × 489 ) / 15

LCM(775,420,489) = 159169500 / 15

LCM(775,420,489) = 10611300


Lets's calculate GCF of 25,99,90

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 10611300/1

Therefore the LCM of Fractions 775/25,420/99,489/90 is 10611300
