Greatest Common Factor
We found the factors 387,794 . The biggest common factor number is the GCF number.
So the greatest common factor 387,794 is 1.
Lets's calculate LCM of 473,851
Given numbers has no common factors except 1. So, there LCM is their product i.e 402523
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/402523
Therefore, the GCF of Fractions 387/473,794/851 is 1/402523
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 473,851 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(473,851) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(473,851) x common factors =1 x 1 = 1
LCM(473,851) = ( 473 × 851 ) / 1
LCM(473,851) = 402523 / 1
LCM(473,851) = 402523
