We found the divisors of 365, 553, 285, 621 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 365, 553, 285, 621 is 1.

Therefore, GCD of numbers 365, 553, 285, 621 is 1

Given Input Data is 365, 553, 285, 621

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 365 is 5 x 73

Prime Factorization of 553 is 7 x 79

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 621 is 3 x 3 x 3 x 23

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(365, 553) = 201845

GCD(365, 553) = ( 365 x 553 ) / 201845

GCD(365, 553) = 201845 / 201845

GCD(365, 553) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 285

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

GCD(1, 285) = 285 / 285

GCD(1, 285) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 621

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

GCD(1, 621) = 621 / 621

GCD(1, 621) = 1

GCD of 365, 553, 285, 621 is 1
