Given numbers are 405, 884, 696, 420

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 884 are 2 x 2 x 13 x 17

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 405, 884, 696, 420

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

Apply this formula for all numbers.

Step1:

LCM(405, 884) = 358020

GCD(405, 884) = ( 405 x 884 ) / 358020

= 405 / 884

= 405

Step2:

LCM(1, 696) = 696

GCD(1, 696) = ( 1 x 696 ) / 696

= 1 / 696

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 405, 884, 696, 420 is 1
