Given numbers are 405, 268, 468, 389

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 268 are 2 x 2 x 67

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

Prime factors of 389 are 389

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

Given numbers are 405, 268, 468, 389

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

Apply this formula for all numbers.

Step1:

LCM(405, 268) = 108540

GCD(405, 268) = ( 405 x 268 ) / 108540

= 405 / 268

= 405

Step2:

LCM(1, 468) = 468

GCD(1, 468) = ( 1 x 468 ) / 468

= 1 / 468

= 1

Step3:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

So, Greatest Common Divisor of 405, 268, 468, 389 is 1
