Given numbers are 311, 400, 405, 205

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

Prime factors of 205 are 5 x 41

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

Given numbers are 311, 400, 405, 205

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

Apply this formula for all numbers.

Step1:

LCM(311, 400) = 124400

GCD(311, 400) = ( 311 x 400 ) / 124400

= 311 / 400

= 311

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 311, 400, 405, 205 is 1
