Given numbers are 865, 720, 114, 819

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 114 are 2 x 3 x 19

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 865, 720, 114, 819

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

Apply this formula for all numbers.

Step1:

LCM(865, 720) = 124560

GCD(865, 720) = ( 865 x 720 ) / 124560

= 865 / 720

= 865

Step2:

LCM(5, 114) = 570

GCD(5, 114) = ( 5 x 114 ) / 570

= 5 / 114

= 5

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 865, 720, 114, 819 is 1
