Least Common Multiple of 705/77,921/729

Given numbers are 705/77,921/729

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 705,921

Least Common Multiple of Numerators i.e. LCM of 705,921 is 216435.

GCF of Denominators means GCF of 77,729 as per the given fractions.

GCF of 77,729 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 705,921

LCM of Fractions 705/77,921/729 is 216435

3 705, 921
235, 307

∴ So the LCM of the given numbers is 3 x 235 x 307 = 216435

Least Common Multiple of 705,921 with GCF Formula

Least Common Multiple of 705,921 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 705,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(705,921) = 3

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

GCF(705,921) x common factors =3 x 1 = 3

LCM(705,921) = ( 705 × 921 ) / 3

LCM(705,921) = 649305 / 3

LCM(705,921) = 216435


Lets's calculate GCF of 77,729

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 216435/1

Therefore the LCM of Fractions 705/77,921/729 is 216435
