Given numbers are 425, 342, 645, 422

The list of prime factors of all numbers are

Prime factors of 425 are 5 x 5 x 17

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 645 are 3 x 5 x 43

Prime factors of 422 are 2 x 211

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

Given numbers are 425, 342, 645, 422

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

Apply this formula for all numbers.

Step1:

LCM(425, 342) = 145350

GCD(425, 342) = ( 425 x 342 ) / 145350

= 425 / 342

= 425

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

So, Greatest Common Divisor of 425, 342, 645, 422 is 1
