Given numbers are 345, 283, 640, 321

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 283 are 283

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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 345, 283, 640, 321

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

Apply this formula for all numbers.

Step1:

LCM(345, 283) = 97635

GCD(345, 283) = ( 345 x 283 ) / 97635

= 345 / 283

= 345

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 321) = 321

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

= 1 / 321

= 1

So, Greatest Common Divisor of 345, 283, 640, 321 is 1
