The list of prime factors of all numbers are

Prime factors of 393 are 3 x 131

Prime factors of 554 are 2 x 277

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 655 are 5 x 131

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

Given numbers are 393, 554, 390, 655

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

Apply this formula for all numbers.

Step1:

LCM(393, 554) = 217722

GCD(393, 554) = ( 393 x 554 ) / 217722

= 393 / 554

= 393

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 393, 554, 390, 655 is 1
