Given numbers are 408, 205, 324, 903

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 205 are 5 x 41

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 903 are 3 x 7 x 43

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 408, 205, 324, 903

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(408, 205) = 83640

GCD(408, 205) = ( 408 x 205 ) / 83640

= 408 / 205

= 408

Step2:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 408, 205, 324, 903 is 1
