The list of prime factors of all numbers are

Prime factors of 388 are 2 x 2 x 97

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 689 are 13 x 53

Prime factors of 344 are 2 x 2 x 2 x 43

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

Given numbers are 388, 756, 689, 344

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

Apply this formula for all numbers.

Step1:

LCM(388, 756) = 73332

GCD(388, 756) = ( 388 x 756 ) / 73332

= 388 / 756

= 388

Step2:

LCM(4, 689) = 2756

GCD(4, 689) = ( 4 x 689 ) / 2756

= 4 / 689

= 4

Step3:

LCM(1, 344) = 344

GCD(1, 344) = ( 1 x 344 ) / 344

= 1 / 344

= 1

So, Greatest Common Divisor of 388, 756, 689, 344 is 1
