Prime factors of 861 are 3 x 7 x 41

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Given numbers are 580, 220, 861, 728

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

Apply this formula for all numbers.

Step1:

LCM(580, 220) = 6380

GCD(580, 220) = ( 580 x 220 ) / 6380

= 580 / 220

= 580

Step2:

LCM(20, 861) = 17220

GCD(20, 861) = ( 20 x 861 ) / 17220

= 20 / 861

= 20

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 580, 220, 861, 728 is 1
