Given numbers are 447, 680, 146, 321

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 146 are 2 x 73

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 447, 680, 146, 321

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

Apply this formula for all numbers.

Step1:

LCM(447, 680) = 303960

GCD(447, 680) = ( 447 x 680 ) / 303960

= 447 / 680

= 447

Step2:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

Step3:

LCM(1, 321) = 321

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

= 1 / 321

= 1

So, Greatest Common Divisor of 447, 680, 146, 321 is 1
