The list of prime factors of all numbers are

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 639 are 3 x 3 x 71

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 396, 468, 639, 434

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

Apply this formula for all numbers.

Step1:

LCM(396, 468) = 5148

GCD(396, 468) = ( 396 x 468 ) / 5148

= 396 / 468

= 396

Step2:

LCM(36, 639) = 2556

GCD(36, 639) = ( 36 x 639 ) / 2556

= 36 / 639

= 36

Step3:

LCM(9, 434) = 3906

GCD(9, 434) = ( 9 x 434 ) / 3906

= 9 / 434

= 9

So, Greatest Common Divisor of 396, 468, 639, 434 is 1
