List of positive integer divisors of 861 that divides 861 without a remainder.
1, 3, 7, 21, 41, 123, 287, 861
Greatest Common Divisior
We found the divisors of 806, 426, 811, 861 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 806, 426, 811, 861 is 1.
Therefore, GCD of numbers 806, 426, 811, 861 is 1
Given Input Data is 806, 426, 811, 861
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 806 is 2 x 13 x 31
Prime Factorization of 426 is 2 x 3 x 71
Prime Factorization of 811 is 811
Prime Factorization of 861 is 3 x 7 x 41
The above numbers do not have any common prime factor. So GCD is 1
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(806, 426) = 171678
GCD(806, 426) = ( 806 x 426 ) / 171678
GCD(806, 426) = 343356 / 171678
GCD(806, 426) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 811
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 811) = 1622
GCD(2, 811) = ( 2 x 811 ) / 1622
GCD(2, 811) = 1622 / 1622
GCD(2, 811) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 861
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
GCD(1, 861) = 861 / 861
GCD(1, 861) = 1
GCD of 806, 426, 811, 861 is 1
