:1,3,5,15,17,51,85,255
Greatest Common Factor
We found the factors 165,255 . The biggest common factor number is the GCF number.
So the greatest common factor 165,255 is 15.
Lets's calculate LCM of 995,553
Given numbers has no common factors except 1. So, there LCM is their product i.e 550235
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/550235
Therefore, the GCF of Fractions 165/995,255/553 is 15/550235
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 995,553 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(995,553) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(995,553) x common factors =1 x 1 = 1
LCM(995,553) = ( 995 × 553 ) / 1
LCM(995,553) = 550235 / 1
LCM(995,553) = 550235
