Given numbers are 283, 764, 891, 720

The list of prime factors of all numbers are

Prime factors of 283 are 283

Prime factors of 764 are 2 x 2 x 191

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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 283, 764, 891, 720

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

Apply this formula for all numbers.

Step1:

LCM(283, 764) = 216212

GCD(283, 764) = ( 283 x 764 ) / 216212

= 283 / 764

= 283

Step2:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 283, 764, 891, 720 is 1
