:1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Greatest Common Factor
We found the factors 996,420 . The biggest common factor number is the GCF number.
So the greatest common factor 996,420 is 12.
Lets's calculate LCM of 20,957
Given numbers has no common factors except 1. So, there LCM is their product i.e 19140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/19140
Therefore, the GCF of Fractions 996/20,420/957 is 12/19140
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 20,957 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,957) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(20,957) x common factors =1 x 1 = 1
LCM(20,957) = ( 20 × 957 ) / 1
LCM(20,957) = 19140 / 1
LCM(20,957) = 19140
