Given numbers are 288, 612, 865, 665

The list of prime factors of all numbers are

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 865 are 5 x 173

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 288, 612, 865, 665

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

Apply this formula for all numbers.

Step1:

LCM(288, 612) = 4896

GCD(288, 612) = ( 288 x 612 ) / 4896

= 288 / 612

= 288

Step2:

LCM(36, 865) = 31140

GCD(36, 865) = ( 36 x 865 ) / 31140

= 36 / 865

= 36

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 288, 612, 865, 665 is 1
