Given numbers are 354, 197, 665, 321

The list of prime factors of all numbers are

Prime factors of 354 are 2 x 3 x 59

Prime factors of 197 are 197

Prime factors of 665 are 5 x 7 x 19

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 354, 197, 665, 321

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

Apply this formula for all numbers.

Step1:

LCM(354, 197) = 69738

GCD(354, 197) = ( 354 x 197 ) / 69738

= 354 / 197

= 354

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 354, 197, 665, 321 is 1
