Given numbers are 330, 490, 388, 693

The list of prime factors of all numbers are

Prime factors of 330 are 2 x 3 x 5 x 11

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

Prime factors of 388 are 2 x 2 x 97

Prime factors of 693 are 3 x 3 x 7 x 11

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

Given numbers are 330, 490, 388, 693

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

Apply this formula for all numbers.

Step1:

LCM(330, 490) = 16170

GCD(330, 490) = ( 330 x 490 ) / 16170

= 330 / 490

= 330

Step2:

LCM(10, 388) = 1940

GCD(10, 388) = ( 10 x 388 ) / 1940

= 10 / 388

= 10

Step3:

LCM(2, 693) = 1386

GCD(2, 693) = ( 2 x 693 ) / 1386

= 2 / 693

= 2

So, Greatest Common Divisor of 330, 490, 388, 693 is 1
