Given numbers are 422, 842, 428, 225

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 842 are 2 x 421

Prime factors of 428 are 2 x 2 x 107

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 422, 842, 428, 225

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

Apply this formula for all numbers.

Step1:

LCM(422, 842) = 177662

GCD(422, 842) = ( 422 x 842 ) / 177662

= 422 / 842

= 422

Step2:

LCM(2, 428) = 428

GCD(2, 428) = ( 2 x 428 ) / 428

= 2 / 428

= 2

Step3:

LCM(2, 225) = 450

GCD(2, 225) = ( 2 x 225 ) / 450

= 2 / 225

= 2

So, Greatest Common Divisor of 422, 842, 428, 225 is 1
