So the greatest common factor 765,570 is 15.
Lets's calculate LCM of 77,717
Given numbers has no common factors except 1. So, there LCM is their product i.e 55209
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/55209
Therefore, the GCF of Fractions 765/77,570/717 is 15/55209
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 77,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,717) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,717) x common factors =1 x 1 = 1
LCM(77,717) = ( 77 × 717 ) / 1
LCM(77,717) = 55209 / 1
LCM(77,717) = 55209
