Lets's calculate LCM of 773,828
Given numbers has no common factors except 1. So, there LCM is their product i.e 640044
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/640044
Therefore, the GCF of Fractions 717/773,4290/828 is 3/640044
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 773,828 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(773,828) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(773,828) x common factors =1 x 1 = 1
LCM(773,828) = ( 773 × 828 ) / 1
LCM(773,828) = 640044 / 1
LCM(773,828) = 640044
