Greatest Common Factor
We found the factors 83,54,709 . The biggest common factor number is the GCF number.
So the greatest common factor 83,54,709 is 1.
Lets's calculate LCM of 251,209,329
Given numbers has no common factors except 1. So, there LCM is their product i.e 17259011
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17259011
Therefore, the GCF of Fractions 83/251,54/209,709/329 is 1/17259011
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 251,209,329 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(251,209,329) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(251,209,329) x common factors =1 x 1 = 1
LCM(251,209,329) = ( 251 × 209 × 329 ) / 1
LCM(251,209,329) = 17259011 / 1
LCM(251,209,329) = 17259011
