Lets's calculate LCM of 743,805
Given numbers has no common factors except 1. So, there LCM is their product i.e 598115
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/598115
Therefore, the GCF of Fractions 456/743,785/805 is 1/598115
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 743,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(743,805) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(743,805) x common factors =1 x 1 = 1
LCM(743,805) = ( 743 × 805 ) / 1
LCM(743,805) = 598115 / 1
LCM(743,805) = 598115
