Greatest Common Factor
We found the factors 785,171 . The biggest common factor number is the GCF number.
So the greatest common factor 785,171 is 1.
Lets's calculate LCM of 239,980
Given numbers has no common factors except 1. So, there LCM is their product i.e 234220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/234220
Therefore, the GCF of Fractions 785/239,171/980 is 1/234220
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 239,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(239,980) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(239,980) x common factors =1 x 1 = 1
LCM(239,980) = ( 239 × 980 ) / 1
LCM(239,980) = 234220 / 1
LCM(239,980) = 234220
