Given numbers are 330, 630, 646, 697

The list of prime factors of all numbers are

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

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 646 are 2 x 17 x 19

Prime factors of 697 are 17 x 41

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

Given numbers are 330, 630, 646, 697

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

Apply this formula for all numbers.

Step1:

LCM(330, 630) = 6930

GCD(330, 630) = ( 330 x 630 ) / 6930

= 330 / 630

= 330

Step2:

LCM(30, 646) = 9690

GCD(30, 646) = ( 30 x 646 ) / 9690

= 30 / 646

= 30

Step3:

LCM(2, 697) = 1394

GCD(2, 697) = ( 2 x 697 ) / 1394

= 2 / 697

= 2

So, Greatest Common Divisor of 330, 630, 646, 697 is 1
