Lets's calculate LCM of 728,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 721448
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/721448
Therefore, the GCF of Fractions 622/728,858/991 is 2/721448
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 728,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(728,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(728,991) x common factors =1 x 1 = 1
LCM(728,991) = ( 728 × 991 ) / 1
LCM(728,991) = 721448 / 1
LCM(728,991) = 721448
