Least Common Multiple of 570/66,210/85,391/643

Given numbers are 570/66,210/85,391/643

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 570,210,391

Least Common Multiple of Numerators i.e. LCM of 570,210,391 is 1560090.

GCF of Denominators means GCF of 66,85,643 as per the given fractions.

GCF of 66,85,643 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 570,210,391

LCM of Fractions 570/66,210/85,391/643 is 1560090

2 570, 210, 391
3 285, 105, 391
5 95, 35, 391
19, 7, 391

∴ So the LCM of the given numbers is 2 x 3 x 5 x 19 x 7 x 391 = 1560090

Least Common Multiple of 570,210,391 with GCF Formula

Least Common Multiple of 570,210,391 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 570,210,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(570,210,391) = 1

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

GCF(570,210,391) x common factors =1 x 30 = 30

LCM(570,210,391) = ( 570 × 210 × 391 ) / 30

LCM(570,210,391) = 46802700 / 30

LCM(570,210,391) = 1560090


Lets's calculate GCF of 66,85,643

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1560090/1

Therefore the LCM of Fractions 570/66,210/85,391/643 is 1560090
