Given numbers are 210, 662, 42, 321

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 662 are 2 x 331

Prime factors of 42 are 2 x 3 x 7

Prime factors of 321 are 3 x 107

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

Given numbers are 210, 662, 42, 321

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

Apply this formula for all numbers.

Step1:

LCM(210, 662) = 69510

GCD(210, 662) = ( 210 x 662 ) / 69510

= 210 / 662

= 210

Step2:

LCM(2, 42) = 42

GCD(2, 42) = ( 2 x 42 ) / 42

= 2 / 42

= 2

Step3:

LCM(2, 321) = 642

GCD(2, 321) = ( 2 x 321 ) / 642

= 2 / 321

= 2

So, Greatest Common Divisor of 210, 662, 42, 321 is 1
