The list of prime factors of all numbers are

Prime factors of 361 are 19 x 19

Prime factors of 645 are 3 x 5 x 43

Prime factors of 434 are 2 x 7 x 31

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 361, 645, 434, 422

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

Apply this formula for all numbers.

Step1:

LCM(361, 645) = 232845

GCD(361, 645) = ( 361 x 645 ) / 232845

= 361 / 645

= 361

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 422) = 422

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

= 1 / 422

= 1

So, Greatest Common Divisor of 361, 645, 434, 422 is 1
