Given numbers are 81/621,55/281,609/786

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 81,55,609

Least Common Multiple of Numerators i.e. LCM of 81,55,609 is 904365.

GCF of Denominators means GCF of 621,281,786 as per the given fractions.

GCF of 621,281,786 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,55,609

LCM of Fractions 81/621,55/281,609/786 is 904365

3 81, 55, 609
27, 55, 203

∴ So the LCM of the given numbers is 3 x 27 x 55 x 203 = 904365

Least Common Multiple of 81,55,609 with GCF Formula

Least Common Multiple of 81,55,609 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 81,55,609 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,55,609) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(81,55,609) x common factors =1 x 3 = 3

LCM(81,55,609) = ( 81 × 55 × 609 ) / 3

LCM(81,55,609) = 2713095 / 3

LCM(81,55,609) = 904365


Lets's calculate GCF of 621,281,786

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 904365/1

Therefore the LCM of Fractions 81/621,55/281,609/786 is 904365
