The list of prime factors of all numbers are

Prime factors of 458 are 2 x 229

Prime factors of 788 are 2 x 2 x 197

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 517 are 11 x 47

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

Given numbers are 458, 788, 280, 517

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

Apply this formula for all numbers.

Step1:

LCM(458, 788) = 180452

GCD(458, 788) = ( 458 x 788 ) / 180452

= 458 / 788

= 458

Step2:

LCM(2, 280) = 280

GCD(2, 280) = ( 2 x 280 ) / 280

= 2 / 280

= 2

Step3:

LCM(2, 517) = 1034

GCD(2, 517) = ( 2 x 517 ) / 1034

= 2 / 517

= 2

So, Greatest Common Divisor of 458, 788, 280, 517 is 1
