Least Common Multiple of 820/42,185/51,721/353

Given numbers are 820/42,185/51,721/353

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 820,185,721

Least Common Multiple of Numerators i.e. LCM of 820,185,721 is 21875140.

GCF of Denominators means GCF of 42,51,353 as per the given fractions.

GCF of 42,51,353 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 820,185,721

LCM of Fractions 820/42,185/51,721/353 is 21875140

5 820, 185, 721
164, 37, 721

∴ So the LCM of the given numbers is 5 x 164 x 37 x 721 = 21875140

Least Common Multiple of 820,185,721 with GCF Formula

Least Common Multiple of 820,185,721 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 820,185,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(820,185,721) = 1

common factors(in case of two or more numbers have common factors) = 5

GCF(820,185,721) x common factors =1 x 5 = 5

LCM(820,185,721) = ( 820 × 185 × 721 ) / 5

LCM(820,185,721) = 109375700 / 5

LCM(820,185,721) = 21875140


Lets's calculate GCF of 42,51,353

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21875140/1

Therefore the LCM of Fractions 820/42,185/51,721/353 is 21875140
