Given numbers are 801/891,210/128,790/620

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 801,210,790

Least Common Multiple of Numerators i.e. LCM of 801,210,790 is 4429530.

GCF of Denominators means GCF of 891,128,620 as per the given fractions.

GCF of 891,128,620 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 801,210,790

LCM of Fractions 801/891,210/128,790/620 is 4429530

2 801, 210, 790
3 801, 105, 395
5 267, 35, 395
267, 7, 79

∴ So the LCM of the given numbers is 2 x 3 x 5 x 267 x 7 x 79 = 4429530

Least Common Multiple of 801,210,790 with GCF Formula

Least Common Multiple of 801,210,790 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 801,210,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(801,210,790) = 1

common factors(in case of two or more numbers have common factors) = 30

GCF(801,210,790) x common factors =1 x 30 = 30

LCM(801,210,790) = ( 801 × 210 × 790 ) / 30

LCM(801,210,790) = 132885900 / 30

LCM(801,210,790) = 4429530


Lets's calculate GCF of 891,128,620

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4429530/1

Therefore the LCM of Fractions 801/891,210/128,790/620 is 4429530
