Lets's calculate LCM of 31,820

Given numbers has no common factors except 1. So, there LCM is their product i.e 25420

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/25420

Therefore, the GCF of Fractions 345/31,3486/820 is 3/25420

Least Common Multiple of 31,820 with GCF Formula

Least Common Multiple of 31,820 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 31,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,820) = 1

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

GCF(31,820) x common factors =1 x 1 = 1

LCM(31,820) = ( 31 × 820 ) / 1

LCM(31,820) = 25420 / 1

LCM(31,820) = 25420
