Given numbers are 561, 128, 454, 570

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 454 are 2 x 227

Prime factors of 570 are 2 x 3 x 5 x 19

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

Given numbers are 561, 128, 454, 570

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

Apply this formula for all numbers.

Step1:

LCM(561, 128) = 71808

GCD(561, 128) = ( 561 x 128 ) / 71808

= 561 / 128

= 561

Step2:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 561, 128, 454, 570 is 1
