Given numbers are 353, 570, 668, 621

The list of prime factors of all numbers are

Prime factors of 353 are 353

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 668 are 2 x 2 x 167

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 353, 570, 668, 621

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

Apply this formula for all numbers.

Step1:

LCM(353, 570) = 201210

GCD(353, 570) = ( 353 x 570 ) / 201210

= 353 / 570

= 353

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 353, 570, 668, 621 is 1
