LCM of:

Least Common Multiple of 840/77,855/5890

Given numbers are 840/77,855/5890

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 840,855

Least Common Multiple of Numerators i.e. LCM of 840,855 is 47880.

GCF of Denominators means GCF of 77,5890 as per the given fractions.

GCF of 77,5890 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 840,855

LCM of Fractions 840/77,855/5890 is 47880

3 840, 855
5 280, 285
56, 57

∴ So the LCM of the given numbers is 3 x 5 x 56 x 57 = 47880

Least Common Multiple of 840,855 with GCF Formula

Least Common Multiple of 840,855 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 840,855 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(840,855) = 15

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

GCF(840,855) x common factors =15 x 1 = 15

LCM(840,855) = ( 840 × 855 ) / 15

LCM(840,855) = 718200 / 15

LCM(840,855) = 47880


Lets's calculate GCF of 77,5890

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 47880/1

Therefore the LCM of Fractions 840/77,855/5890 is 47880
