:1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 624,861 . The biggest common factor number is the GCF number.
So the greatest common factor 624,861 is 3.
Lets's calculate LCM of 495,799
Given numbers has no common factors except 1. So, there LCM is their product i.e 395505
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/395505
Therefore, the GCF of Fractions 624/495,861/799 is 3/395505
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 495,799 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(495,799) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(495,799) x common factors =1 x 1 = 1
LCM(495,799) = ( 495 × 799 ) / 1
LCM(495,799) = 395505 / 1
LCM(495,799) = 395505
