1,17,289
Greatest Common Factor
We found the factors 229,420,289 . The biggest common factor number is the GCF number.
So the greatest common factor 229,420,289 is 1.
Lets's calculate LCM of 865,768,821
Given numbers has no common factors except 1. So, there LCM is their product i.e 545406720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/545406720
Therefore, the GCF of Fractions 229/865,420/768,289/821 is 1/545406720
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 865,768,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(865,768,821) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(865,768,821) x common factors =1 x 1 = 1
LCM(865,768,821) = ( 865 × 768 × 821 ) / 1
LCM(865,768,821) = 545406720 / 1
LCM(865,768,821) = 545406720
