Greatest Common Factor
We found the factors 3117,1512 . The biggest common factor number is the GCF number.
So the greatest common factor 3117,1512 is 3.
Lets's calculate LCM of 79,828
Given numbers has no common factors except 1. So, there LCM is their product i.e 65412
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/65412
Therefore, the GCF of Fractions 3117/79,1512/828 is 3/65412
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 79,828 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,828) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,828) x common factors =1 x 1 = 1
LCM(79,828) = ( 79 × 828 ) / 1
LCM(79,828) = 65412 / 1
LCM(79,828) = 65412
