The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 395 are 5 x 79

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 844 are 2 x 2 x 211

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

Given numbers are 561, 395, 784, 844

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

Apply this formula for all numbers.

Step1:

LCM(561, 395) = 221595

GCD(561, 395) = ( 561 x 395 ) / 221595

= 561 / 395

= 561

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 844) = 844

GCD(1, 844) = ( 1 x 844 ) / 844

= 1 / 844

= 1

So, Greatest Common Divisor of 561, 395, 784, 844 is 1
