Given numbers are 561, 230, 568, 225

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 568 are 2 x 2 x 2 x 71

Prime factors of 225 are 3 x 3 x 5 x 5

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

Given numbers are 561, 230, 568, 225

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, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 561, 230, 568, 225 is 1
