Greatest Common Factor
We found the factors 255,346 . The biggest common factor number is the GCF number.
So the greatest common factor 255,346 is 1.
Lets's calculate LCM of 405,806
Given numbers has no common factors except 1. So, there LCM is their product i.e 326430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/326430
Therefore, the GCF of Fractions 255/405,346/806 is 1/326430
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 405,806 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(405,806) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(405,806) x common factors =1 x 1 = 1
LCM(405,806) = ( 405 × 806 ) / 1
LCM(405,806) = 326430 / 1
LCM(405,806) = 326430
