Greatest Common Factor
We found the factors 731,477 . The biggest common factor number is the GCF number.
So the greatest common factor 731,477 is 1.
Lets's calculate LCM of 285,778
Given numbers has no common factors except 1. So, there LCM is their product i.e 221730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/221730
Therefore, the GCF of Fractions 731/285,477/778 is 1/221730
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 285,778 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(285,778) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(285,778) x common factors =1 x 1 = 1
LCM(285,778) = ( 285 × 778 ) / 1
LCM(285,778) = 221730 / 1
LCM(285,778) = 221730
