Given numbers are 405, 765, 908, 505

The list of prime factors of all numbers are

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

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

Prime factors of 908 are 2 x 2 x 227

Prime factors of 505 are 5 x 101

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

Given numbers are 405, 765, 908, 505

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

Apply this formula for all numbers.

Step1:

LCM(405, 765) = 6885

GCD(405, 765) = ( 405 x 765 ) / 6885

= 405 / 765

= 405

Step2:

LCM(45, 908) = 40860

GCD(45, 908) = ( 45 x 908 ) / 40860

= 45 / 908

= 45

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 405, 765, 908, 505 is 1
