Given numbers are 121, 730, 255, 689

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 730 are 2 x 5 x 73

Prime factors of 255 are 3 x 5 x 17

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 121, 730, 255, 689

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

Apply this formula for all numbers.

Step1:

LCM(121, 730) = 88330

GCD(121, 730) = ( 121 x 730 ) / 88330

= 121 / 730

= 121

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

Step3:

LCM(1, 689) = 689

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

= 1 / 689

= 1

So, Greatest Common Divisor of 121, 730, 255, 689 is 1
