The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 275 are 5 x 5 x 11

Prime factors of 689 are 13 x 53

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 445, 275, 689, 688

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

Apply this formula for all numbers.

Step1:

LCM(445, 275) = 24475

GCD(445, 275) = ( 445 x 275 ) / 24475

= 445 / 275

= 445

Step2:

LCM(5, 689) = 3445

GCD(5, 689) = ( 5 x 689 ) / 3445

= 5 / 689

= 5

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 445, 275, 689, 688 is 1
