Given numbers are 396, 405, 815, 787

The list of prime factors of all numbers are

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

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

Prime factors of 815 are 5 x 163

Prime factors of 787 are 787

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

Given numbers are 396, 405, 815, 787

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

Apply this formula for all numbers.

Step1:

LCM(396, 405) = 17820

GCD(396, 405) = ( 396 x 405 ) / 17820

= 396 / 405

= 396

Step2:

LCM(9, 815) = 7335

GCD(9, 815) = ( 9 x 815 ) / 7335

= 9 / 815

= 9

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 396, 405, 815, 787 is 1
