Given numbers are 406, 743, 286, 405

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 743 are 743

Prime factors of 286 are 2 x 11 x 13

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

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

Given numbers are 406, 743, 286, 405

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

Apply this formula for all numbers.

Step1:

LCM(406, 743) = 301658

GCD(406, 743) = ( 406 x 743 ) / 301658

= 406 / 743

= 406

Step2:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

Step3:

LCM(1, 405) = 405

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

= 1 / 405

= 1

So, Greatest Common Divisor of 406, 743, 286, 405 is 1
