The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 622 are 2 x 311

Prime factors of 790 are 2 x 5 x 79

Prime factors of 515 are 5 x 103

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

Given numbers are 842, 622, 790, 515

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

Apply this formula for all numbers.

Step1:

LCM(842, 622) = 261862

GCD(842, 622) = ( 842 x 622 ) / 261862

= 842 / 622

= 842

Step2:

LCM(2, 790) = 790

GCD(2, 790) = ( 2 x 790 ) / 790

= 2 / 790

= 2

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 842, 622, 790, 515 is 1
