Given numbers are 405, 471, 285, 227

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 471 are 3 x 157

Prime factors of 285 are 3 x 5 x 19

Prime factors of 227 are 227

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

Given numbers are 405, 471, 285, 227

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

Apply this formula for all numbers.

Step1:

LCM(405, 471) = 63585

GCD(405, 471) = ( 405 x 471 ) / 63585

= 405 / 471

= 405

Step2:

LCM(3, 285) = 285

GCD(3, 285) = ( 3 x 285 ) / 285

= 3 / 285

= 3

Step3:

LCM(3, 227) = 681

GCD(3, 227) = ( 3 x 227 ) / 681

= 3 / 227

= 3

So, Greatest Common Divisor of 405, 471, 285, 227 is 1
