Given numbers are 620, 170, 772, 517

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 170 are 2 x 5 x 17

Prime factors of 772 are 2 x 2 x 193

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 620, 170, 772, 517

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

Apply this formula for all numbers.

Step1:

LCM(620, 170) = 10540

GCD(620, 170) = ( 620 x 170 ) / 10540

= 620 / 170

= 620

Step2:

LCM(10, 772) = 3860

GCD(10, 772) = ( 10 x 772 ) / 3860

= 10 / 772

= 10

Step3:

LCM(2, 517) = 1034

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

= 2 / 517

= 2

So, Greatest Common Divisor of 620, 170, 772, 517 is 1
