The list of prime factors of all numbers are

Prime factors of 993 are 3 x 331

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 646 are 2 x 17 x 19

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 993, 520, 646, 768

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

Apply this formula for all numbers.

Step1:

LCM(993, 520) = 516360

GCD(993, 520) = ( 993 x 520 ) / 516360

= 993 / 520

= 993

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 993, 520, 646, 768 is 1
