Given numbers are 580, 765, 261, 656

The list of prime factors of all numbers are

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 261 are 3 x 3 x 29

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 580, 765, 261, 656

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

Apply this formula for all numbers.

Step1:

LCM(580, 765) = 88740

GCD(580, 765) = ( 580 x 765 ) / 88740

= 580 / 765

= 580

Step2:

LCM(5, 261) = 1305

GCD(5, 261) = ( 5 x 261 ) / 1305

= 5 / 261

= 5

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 580, 765, 261, 656 is 1
