Lets's calculate LCM of 707,795
Given numbers has no common factors except 1. So, there LCM is their product i.e 562065
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/562065
Therefore, the GCF of Fractions 7821/707,4840/795 is 11/562065
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 707,795 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(707,795) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(707,795) x common factors =1 x 1 = 1
LCM(707,795) = ( 707 × 795 ) / 1
LCM(707,795) = 562065 / 1
LCM(707,795) = 562065
