Given numbers are 255, 393, 684, 505

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 393 are 3 x 131

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 505 are 5 x 101

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

Given numbers are 255, 393, 684, 505

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

Apply this formula for all numbers.

Step1:

LCM(255, 393) = 33405

GCD(255, 393) = ( 255 x 393 ) / 33405

= 255 / 393

= 255

Step2:

LCM(3, 684) = 684

GCD(3, 684) = ( 3 x 684 ) / 684

= 3 / 684

= 3

Step3:

LCM(3, 505) = 1515

GCD(3, 505) = ( 3 x 505 ) / 1515

= 3 / 505

= 3

So, Greatest Common Divisor of 255, 393, 684, 505 is 1
