Given numbers are 580, 564, 81, 585

The list of prime factors of all numbers are

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

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 81 are 3 x 3 x 3 x 3

Prime factors of 585 are 3 x 3 x 5 x 13

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

Given numbers are 580, 564, 81, 585

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

Apply this formula for all numbers.

Step1:

LCM(580, 564) = 81780

GCD(580, 564) = ( 580 x 564 ) / 81780

= 580 / 564

= 580

Step2:

LCM(4, 81) = 324

GCD(4, 81) = ( 4 x 81 ) / 324

= 4 / 81

= 4

Step3:

LCM(1, 585) = 585

GCD(1, 585) = ( 1 x 585 ) / 585

= 1 / 585

= 1

So, Greatest Common Divisor of 580, 564, 81, 585 is 1
