The list of prime factors of all numbers are

Prime factors of 553 are 7 x 79

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 553, 396, 621, 288

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

Apply this formula for all numbers.

Step1:

LCM(553, 396) = 218988

GCD(553, 396) = ( 553 x 396 ) / 218988

= 553 / 396

= 553

Step2:

LCM(1, 621) = 621

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

= 1 / 621

= 1

Step3:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

So, Greatest Common Divisor of 553, 396, 621, 288 is 1
