Given numbers are 765, 865, 570, 988

The list of prime factors of all numbers are

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

Prime factors of 865 are 5 x 173

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 988 are 2 x 2 x 13 x 19

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

Given numbers are 765, 865, 570, 988

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

Apply this formula for all numbers.

Step1:

LCM(765, 865) = 132345

GCD(765, 865) = ( 765 x 865 ) / 132345

= 765 / 865

= 765

Step2:

LCM(5, 570) = 570

GCD(5, 570) = ( 5 x 570 ) / 570

= 5 / 570

= 5

Step3:

LCM(5, 988) = 4940

GCD(5, 988) = ( 5 x 988 ) / 4940

= 5 / 988

= 5

So, Greatest Common Divisor of 765, 865, 570, 988 is 1
