Given numbers are 765, 405, 692, 155

The list of prime factors of all numbers are

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

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

Prime factors of 692 are 2 x 2 x 173

Prime factors of 155 are 5 x 31

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

Given numbers are 765, 405, 692, 155

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

Apply this formula for all numbers.

Step1:

LCM(765, 405) = 6885

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

= 765 / 405

= 765

Step2:

LCM(45, 692) = 31140

GCD(45, 692) = ( 45 x 692 ) / 31140

= 45 / 692

= 45

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 765, 405, 692, 155 is 1
