1, 571
Greatest Common Divisior
We found the divisors of 87, 819, 187, 571 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 87, 819, 187, 571 is 1.
Therefore, GCD of numbers 87, 819, 187, 571 is 1
Given Input Data is 87, 819, 187, 571
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 87 is 3 x 29
Prime Factorization of 819 is 3 x 3 x 7 x 13
Prime Factorization of 187 is 11 x 17
Prime Factorization of 571 is 571
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(87, 819) = 23751
GCD(87, 819) = ( 87 x 819 ) / 23751
GCD(87, 819) = 71253 / 23751
GCD(87, 819) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 187
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 187) = 561
GCD(3, 187) = ( 3 x 187 ) / 561
GCD(3, 187) = 561 / 561
GCD(3, 187) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 571
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 571) = 571
GCD(1, 571) = ( 1 x 571 ) / 571
GCD(1, 571) = 571 / 571
GCD(1, 571) = 1
GCD of 87, 819, 187, 571 is 1
