Given numbers are 344, 788, 458, 689

The list of prime factors of all numbers are

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

Prime factors of 788 are 2 x 2 x 197

Prime factors of 458 are 2 x 229

Prime factors of 689 are 13 x 53

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

Given numbers are 344, 788, 458, 689

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

Apply this formula for all numbers.

Step1:

LCM(344, 788) = 67768

GCD(344, 788) = ( 344 x 788 ) / 67768

= 344 / 788

= 344

Step2:

LCM(4, 458) = 916

GCD(4, 458) = ( 4 x 458 ) / 916

= 4 / 458

= 4

Step3:

LCM(2, 689) = 1378

GCD(2, 689) = ( 2 x 689 ) / 1378

= 2 / 689

= 2

So, Greatest Common Divisor of 344, 788, 458, 689 is 1
