:1,2,17,19,34,38,323,646
Greatest Common Factor
We found the factors 650,646 . The biggest common factor number is the GCF number.
So the greatest common factor 650,646 is 2.
Lets's calculate LCM of 472,361
Given numbers has no common factors except 1. So, there LCM is their product i.e 170392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/170392
Therefore, the GCF of Fractions 650/472,646/361 is 2/170392
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 472,361 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,361) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(472,361) x common factors =1 x 1 = 1
LCM(472,361) = ( 472 × 361 ) / 1
LCM(472,361) = 170392 / 1
LCM(472,361) = 170392
