:1,5,61,305
Greatest Common Factor
We found the factors 420,305 . The biggest common factor number is the GCF number.
So the greatest common factor 420,305 is 5.
Lets's calculate LCM of 47,5254
Given numbers has no common factors except 1. So, there LCM is their product i.e 246938
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/246938
Therefore, the GCF of Fractions 420/47,305/5254 is 5/246938
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 47,5254 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,5254) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,5254) x common factors =1 x 1 = 1
LCM(47,5254) = ( 47 × 5254 ) / 1
LCM(47,5254) = 246938 / 1
LCM(47,5254) = 246938
