Lets's calculate LCM of 766,823
Given numbers has no common factors except 1. So, there LCM is their product i.e 630418
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/630418
Therefore, the GCF of Fractions 989/766,778/823 is 1/630418
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 766,823 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(766,823) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(766,823) x common factors =1 x 1 = 1
LCM(766,823) = ( 766 × 823 ) / 1
LCM(766,823) = 630418 / 1
LCM(766,823) = 630418
