Given numbers are 405, 408, 447, 307

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 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 447 are 3 x 149

Prime factors of 307 are 307

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

Given numbers are 405, 408, 447, 307

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

Apply this formula for all numbers.

Step1:

LCM(405, 408) = 55080

GCD(405, 408) = ( 405 x 408 ) / 55080

= 405 / 408

= 405

Step2:

LCM(3, 447) = 447

GCD(3, 447) = ( 3 x 447 ) / 447

= 3 / 447

= 3

Step3:

LCM(3, 307) = 921

GCD(3, 307) = ( 3 x 307 ) / 921

= 3 / 307

= 3

So, Greatest Common Divisor of 405, 408, 447, 307 is 1
