Given numbers are 395, 728, 471, 765

The list of prime factors of all numbers are

Prime factors of 395 are 5 x 79

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 471 are 3 x 157

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

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

Given numbers are 395, 728, 471, 765

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

Apply this formula for all numbers.

Step1:

LCM(395, 728) = 287560

GCD(395, 728) = ( 395 x 728 ) / 287560

= 395 / 728

= 395

Step2:

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

= 1 / 471

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 395, 728, 471, 765 is 1
