Given numbers are 203, 523, 442, 128

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 523 are 523

Prime factors of 442 are 2 x 13 x 17

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

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

Given numbers are 203, 523, 442, 128

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

Apply this formula for all numbers.

Step1:

LCM(203, 523) = 106169

GCD(203, 523) = ( 203 x 523 ) / 106169

= 203 / 523

= 203

Step2:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 203, 523, 442, 128 is 1
