Given numbers are 765, 975, 405, 403

The list of prime factors of all numbers are

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 975 are 3 x 5 x 5 x 13

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

Prime factors of 403 are 13 x 31

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

Given numbers are 765, 975, 405, 403

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

Apply this formula for all numbers.

Step1:

LCM(765, 975) = 49725

GCD(765, 975) = ( 765 x 975 ) / 49725

= 765 / 975

= 765

Step2:

LCM(15, 405) = 405

GCD(15, 405) = ( 15 x 405 ) / 405

= 15 / 405

= 15

Step3:

LCM(15, 403) = 6045

GCD(15, 403) = ( 15 x 403 ) / 6045

= 15 / 403

= 15

So, Greatest Common Divisor of 765, 975, 405, 403 is 1
