Given numbers are 561, 230, 111, 581

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 230 are 2 x 5 x 23

Prime factors of 111 are 3 x 37

Prime factors of 581 are 7 x 83

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

Given numbers are 561, 230, 111, 581

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

Apply this formula for all numbers.

Step1:

LCM(561, 230) = 129030

GCD(561, 230) = ( 561 x 230 ) / 129030

= 561 / 230

= 561

Step2:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 561, 230, 111, 581 is 1
