Given numbers are 821, 390, 405, 935

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 390 are 2 x 3 x 5 x 13

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

Prime factors of 935 are 5 x 11 x 17

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

Given numbers are 821, 390, 405, 935

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

Apply this formula for all numbers.

Step1:

LCM(821, 390) = 320190

GCD(821, 390) = ( 821 x 390 ) / 320190

= 821 / 390

= 821

Step2:

LCM(1, 405) = 405

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

= 1 / 405

= 1

Step3:

LCM(1, 935) = 935

GCD(1, 935) = ( 1 x 935 ) / 935

= 1 / 935

= 1

So, Greatest Common Divisor of 821, 390, 405, 935 is 1
