So the greatest common factor 748,686 is 2.
Lets's calculate LCM of 308,339
Given numbers has no common factors except 1. So, there LCM is their product i.e 104412
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/104412
Therefore, the GCF of Fractions 748/308,686/339 is 2/104412
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 308,339 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(308,339) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(308,339) x common factors =1 x 1 = 1
LCM(308,339) = ( 308 × 339 ) / 1
LCM(308,339) = 104412 / 1
LCM(308,339) = 104412
