Given numbers are 331, 790, 510, 405

The list of prime factors of all numbers are

Prime factors of 331 are 331

Prime factors of 790 are 2 x 5 x 79

Prime factors of 510 are 2 x 3 x 5 x 17

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 331, 790, 510, 405

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

Apply this formula for all numbers.

Step1:

LCM(331, 790) = 261490

GCD(331, 790) = ( 331 x 790 ) / 261490

= 331 / 790

= 331

Step2:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

Step3:

LCM(1, 405) = 405

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

= 1 / 405

= 1

So, Greatest Common Divisor of 331, 790, 510, 405 is 1
