Greatest Common Factor
We found the factors 66,819,865 . The biggest common factor number is the GCF number.
So the greatest common factor 66,819,865 is 1.
Lets's calculate LCM of 31,39,829
Given numbers has no common factors except 1. So, there LCM is their product i.e 1002261
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1002261
Therefore, the GCF of Fractions 66/31,819/39,865/829 is 1/1002261
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 31,39,829 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,39,829) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,39,829) x common factors =1 x 1 = 1
LCM(31,39,829) = ( 31 × 39 × 829 ) / 1
LCM(31,39,829) = 1002261 / 1
LCM(31,39,829) = 1002261
