Greatest Common Factor
We found the factors 790,7728 . The biggest common factor number is the GCF number.
So the greatest common factor 790,7728 is 2.
Lets's calculate LCM of 661,335
Given numbers has no common factors except 1. So, there LCM is their product i.e 221435
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/221435
Therefore, the GCF of Fractions 790/661,7728/335 is 2/221435
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 661,335 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(661,335) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(661,335) x common factors =1 x 1 = 1
LCM(661,335) = ( 661 × 335 ) / 1
LCM(661,335) = 221435 / 1
LCM(661,335) = 221435
