Lets's calculate LCM of 509,823
Given numbers has no common factors except 1. So, there LCM is their product i.e 418907
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/418907
Therefore, the GCF of Fractions 865/509,988/823 is 1/418907
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 509,823 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(509,823) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(509,823) x common factors =1 x 1 = 1
LCM(509,823) = ( 509 × 823 ) / 1
LCM(509,823) = 418907 / 1
LCM(509,823) = 418907
