Greatest Common Factor
We found the factors 447,821 . The biggest common factor number is the GCF number.
So the greatest common factor 447,821 is 1.
Lets's calculate LCM of 856,623
Given numbers has no common factors except 1. So, there LCM is their product i.e 533288
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/533288
Therefore, the GCF of Fractions 447/856,821/623 is 1/533288
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 856,623 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(856,623) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(856,623) x common factors =1 x 1 = 1
LCM(856,623) = ( 856 × 623 ) / 1
LCM(856,623) = 533288 / 1
LCM(856,623) = 533288
