Given numbers are 303, 490, 497, 689

The list of prime factors of all numbers are

Prime factors of 303 are 3 x 101

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 497 are 7 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 303, 490, 497, 689

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

Apply this formula for all numbers.

Step1:

LCM(303, 490) = 148470

GCD(303, 490) = ( 303 x 490 ) / 148470

= 303 / 490

= 303

Step2:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

Step3:

LCM(1, 689) = 689

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

= 1 / 689

= 1

So, Greatest Common Divisor of 303, 490, 497, 689 is 1
