Given numbers are 405, 621, 252, 443

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 621 are 3 x 3 x 3 x 23

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 443 are 443

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

Given numbers are 405, 621, 252, 443

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

Apply this formula for all numbers.

Step1:

LCM(405, 621) = 9315

GCD(405, 621) = ( 405 x 621 ) / 9315

= 405 / 621

= 405

Step2:

LCM(27, 252) = 756

GCD(27, 252) = ( 27 x 252 ) / 756

= 27 / 252

= 27

Step3:

LCM(9, 443) = 3987

GCD(9, 443) = ( 9 x 443 ) / 3987

= 9 / 443

= 9

So, Greatest Common Divisor of 405, 621, 252, 443 is 1
