:1,3,7,11,21,33,77,231
Greatest Common Factor
We found the factors 20,213,231 . The biggest common factor number is the GCF number.
So the greatest common factor 20,213,231 is 1.
Lets's calculate LCM of 34,39,355
Given numbers has no common factors except 1. So, there LCM is their product i.e 470730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/470730
Therefore, the GCF of Fractions 20/34,213/39,231/355 is 1/470730
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 34,39,355 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(34,39,355) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(34,39,355) x common factors =1 x 1 = 1
LCM(34,39,355) = ( 34 × 39 × 355 ) / 1
LCM(34,39,355) = 470730 / 1
LCM(34,39,355) = 470730
