The list of prime factors of all numbers are

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

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 862 are 2 x 431

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 765, 672, 862, 128

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

Apply this formula for all numbers.

Step1:

LCM(765, 672) = 171360

GCD(765, 672) = ( 765 x 672 ) / 171360

= 765 / 672

= 765

Step2:

LCM(3, 862) = 2586

GCD(3, 862) = ( 3 x 862 ) / 2586

= 3 / 862

= 3

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 765, 672, 862, 128 is 1
