Given numbers are 258, 789, 780, 322

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 789 are 3 x 263

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 322 are 2 x 7 x 23

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

Given numbers are 258, 789, 780, 322

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

Apply this formula for all numbers.

Step1:

LCM(258, 789) = 67854

GCD(258, 789) = ( 258 x 789 ) / 67854

= 258 / 789

= 258

Step2:

LCM(3, 780) = 780

GCD(3, 780) = ( 3 x 780 ) / 780

= 3 / 780

= 3

Step3:

LCM(3, 322) = 966

GCD(3, 322) = ( 3 x 322 ) / 966

= 3 / 322

= 3

So, Greatest Common Divisor of 258, 789, 780, 322 is 1
