The list of prime factors of all numbers are

Prime factors of 581 are 7 x 83

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

Prime factors of 798 are 2 x 3 x 7 x 19

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 581, 784, 798, 688

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

Apply this formula for all numbers.

Step1:

LCM(581, 784) = 65072

GCD(581, 784) = ( 581 x 784 ) / 65072

= 581 / 784

= 581

Step2:

LCM(7, 798) = 798

GCD(7, 798) = ( 7 x 798 ) / 798

= 7 / 798

= 7

Step3:

LCM(7, 688) = 4816

GCD(7, 688) = ( 7 x 688 ) / 4816

= 7 / 688

= 7

So, Greatest Common Divisor of 581, 784, 798, 688 is 1
