Given numbers are 321, 447, 706, 644

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 447 are 3 x 149

Prime factors of 706 are 2 x 353

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 321, 447, 706, 644

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

Apply this formula for all numbers.

Step1:

LCM(321, 447) = 47829

GCD(321, 447) = ( 321 x 447 ) / 47829

= 321 / 447

= 321

Step2:

LCM(3, 706) = 2118

GCD(3, 706) = ( 3 x 706 ) / 2118

= 3 / 706

= 3

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 321, 447, 706, 644 is 1
