1,683
Factors of 504
List of positive integer factors of 504 that divides 504 without a remainder.
1,2,3,4,6,7,8,9,12,14,18,21,24,28,36,42,56,63,72,84,126,168,252,504
Greatest Common Factor
We found the factors 518,683,504 . The biggest common factor number is the GCF number.
So the greatest common factor 518,683,504 is 1.
Lets's calculate LCM of 21,31,107
Given numbers has no common factors except 1. So, there LCM is their product i.e 69657
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/69657
Therefore, the GCF of Fractions 518/21,683/31,504/107 is 1/69657
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 21,31,107 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,31,107) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,31,107) x common factors =1 x 1 = 1
LCM(21,31,107) = ( 21 × 31 × 107 ) / 1
LCM(21,31,107) = 69657 / 1
LCM(21,31,107) = 69657
