Given numbers are 520, 725, 785, 817

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 725 are 5 x 5 x 29

Prime factors of 785 are 5 x 157

Prime factors of 817 are 19 x 43

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

Given numbers are 520, 725, 785, 817

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

Apply this formula for all numbers.

Step1:

LCM(520, 725) = 75400

GCD(520, 725) = ( 520 x 725 ) / 75400

= 520 / 725

= 520

Step2:

LCM(5, 785) = 785

GCD(5, 785) = ( 5 x 785 ) / 785

= 5 / 785

= 5

Step3:

LCM(5, 817) = 4085

GCD(5, 817) = ( 5 x 817 ) / 4085

= 5 / 817

= 5

So, Greatest Common Divisor of 520, 725, 785, 817 is 1
