Given numbers are 720, 861, 696, 775

The list of prime factors of all numbers are

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

Prime factors of 861 are 3 x 7 x 41

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

Prime factors of 775 are 5 x 5 x 31

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

Given numbers are 720, 861, 696, 775

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

Apply this formula for all numbers.

Step1:

LCM(720, 861) = 206640

GCD(720, 861) = ( 720 x 861 ) / 206640

= 720 / 861

= 720

Step2:

LCM(3, 696) = 696

GCD(3, 696) = ( 3 x 696 ) / 696

= 3 / 696

= 3

Step3:

LCM(3, 775) = 2325

GCD(3, 775) = ( 3 x 775 ) / 2325

= 3 / 775

= 3

So, Greatest Common Divisor of 720, 861, 696, 775 is 1
