Greatest Common Factor

We found the factors 80,871 . The biggest common factor number is the GCF number.
So the greatest common factor 80,871 is 1.

Lets's calculate LCM of 396,810

2 396, 810
3 198, 405
3 66, 135
22, 45

∴ So the LCM of the given numbers is 2 x 3 x 3 x 22 x 45 = 17820

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17820

Therefore, the GCF of Fractions 80/396,871/810 is 1/17820

Least Common Multiple of 396,810 with GCF Formula

Least Common Multiple of 396,810 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 396,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(396,810) = 18

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

GCF(396,810) x common factors =18 x 1 = 18

LCM(396,810) = ( 396 × 810 ) / 18

LCM(396,810) = 320760 / 18

LCM(396,810) = 17820
