Given numbers are 720, 717, 774, 257

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 717 are 3 x 239

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 257 are 257

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

Given numbers are 720, 717, 774, 257

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

Apply this formula for all numbers.

Step1:

LCM(720, 717) = 172080

GCD(720, 717) = ( 720 x 717 ) / 172080

= 720 / 717

= 720

Step2:

LCM(3, 774) = 774

GCD(3, 774) = ( 3 x 774 ) / 774

= 3 / 774

= 3

Step3:

LCM(3, 257) = 771

GCD(3, 257) = ( 3 x 257 ) / 771

= 3 / 257

= 3

So, Greatest Common Divisor of 720, 717, 774, 257 is 1
