Given numbers are 872, 728, 695, 720

The list of prime factors of all numbers are

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

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 695 are 5 x 139

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

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

Given numbers are 872, 728, 695, 720

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

Apply this formula for all numbers.

Step1:

LCM(872, 728) = 79352

GCD(872, 728) = ( 872 x 728 ) / 79352

= 872 / 728

= 872

Step2:

LCM(8, 695) = 5560

GCD(8, 695) = ( 8 x 695 ) / 5560

= 8 / 695

= 8

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 872, 728, 695, 720 is 1
