Given numbers are 658, 585, 789, 405

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 585 are 3 x 3 x 5 x 13

Prime factors of 789 are 3 x 263

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 658, 585, 789, 405

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

Apply this formula for all numbers.

Step1:

LCM(658, 585) = 384930

GCD(658, 585) = ( 658 x 585 ) / 384930

= 658 / 585

= 658

Step2:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

Step3:

LCM(1, 405) = 405

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

= 1 / 405

= 1

So, Greatest Common Divisor of 658, 585, 789, 405 is 1
