Given numbers are 605, 261, 723, 520

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 261 are 3 x 3 x 29

Prime factors of 723 are 3 x 241

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

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

Given numbers are 605, 261, 723, 520

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

Apply this formula for all numbers.

Step1:

LCM(605, 261) = 157905

GCD(605, 261) = ( 605 x 261 ) / 157905

= 605 / 261

= 605

Step2:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 605, 261, 723, 520 is 1
