The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 230 are 2 x 5 x 23

Prime factors of 781 are 11 x 71

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 355, 230, 781, 689

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

Apply this formula for all numbers.

Step1:

LCM(355, 230) = 16330

GCD(355, 230) = ( 355 x 230 ) / 16330

= 355 / 230

= 355

Step2:

LCM(5, 781) = 3905

GCD(5, 781) = ( 5 x 781 ) / 3905

= 5 / 781

= 5

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 355, 230, 781, 689 is 1
