So the greatest common factor 511,868 is 7.
Lets's calculate LCM of 465,823
Given numbers has no common factors except 1. So, there LCM is their product i.e 382695
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/382695
Therefore, the GCF of Fractions 511/465,868/823 is 7/382695
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 465,823 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(465,823) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(465,823) x common factors =1 x 1 = 1
LCM(465,823) = ( 465 × 823 ) / 1
LCM(465,823) = 382695 / 1
LCM(465,823) = 382695
