The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

Prime factors of 654 are 2 x 3 x 109

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 445 are 5 x 89

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

Given numbers are 722, 654, 256, 445

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

Apply this formula for all numbers.

Step1:

LCM(722, 654) = 236094

GCD(722, 654) = ( 722 x 654 ) / 236094

= 722 / 654

= 722

Step2:

LCM(2, 256) = 256

GCD(2, 256) = ( 2 x 256 ) / 256

= 2 / 256

= 2

Step3:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

So, Greatest Common Divisor of 722, 654, 256, 445 is 1
