Greatest Common Factor
We found the factors 20,8612 . The biggest common factor number is the GCF number.
So the greatest common factor 20,8612 is 4.
Lets's calculate LCM of 421,3885
Given numbers has no common factors except 1. So, there LCM is their product i.e 1635585
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1635585
Therefore, the GCF of Fractions 20/421,8612/3885 is 4/1635585
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 421,3885 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,3885) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(421,3885) x common factors =1 x 1 = 1
LCM(421,3885) = ( 421 × 3885 ) / 1
LCM(421,3885) = 1635585 / 1
LCM(421,3885) = 1635585
