Given numbers are 530, 770, 485, 788

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 485 are 5 x 97

Prime factors of 788 are 2 x 2 x 197

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

Given numbers are 530, 770, 485, 788

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

Apply this formula for all numbers.

Step1:

LCM(530, 770) = 40810

GCD(530, 770) = ( 530 x 770 ) / 40810

= 530 / 770

= 530

Step2:

LCM(10, 485) = 970

GCD(10, 485) = ( 10 x 485 ) / 970

= 10 / 485

= 10

Step3:

LCM(5, 788) = 3940

GCD(5, 788) = ( 5 x 788 ) / 3940

= 5 / 788

= 5

So, Greatest Common Divisor of 530, 770, 485, 788 is 1
