Given numbers are 800, 665, 515, 872

The list of prime factors of all numbers are

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 665 are 5 x 7 x 19

Prime factors of 515 are 5 x 103

Prime factors of 872 are 2 x 2 x 2 x 109

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

Given numbers are 800, 665, 515, 872

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

Apply this formula for all numbers.

Step1:

LCM(800, 665) = 106400

GCD(800, 665) = ( 800 x 665 ) / 106400

= 800 / 665

= 800

Step2:

LCM(5, 515) = 515

GCD(5, 515) = ( 5 x 515 ) / 515

= 5 / 515

= 5

Step3:

LCM(5, 872) = 4360

GCD(5, 872) = ( 5 x 872 ) / 4360

= 5 / 872

= 5

So, Greatest Common Divisor of 800, 665, 515, 872 is 1
