Greatest Common Factor
We found the factors 856,821 . The biggest common factor number is the GCF number.
So the greatest common factor 856,821 is 1.
Lets's calculate LCM of 493,959
Given numbers has no common factors except 1. So, there LCM is their product i.e 472787
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/472787
Therefore, the GCF of Fractions 856/493,821/959 is 1/472787
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 493,959 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(493,959) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(493,959) x common factors =1 x 1 = 1
LCM(493,959) = ( 493 × 959 ) / 1
LCM(493,959) = 472787 / 1
LCM(493,959) = 472787
