Given numbers are 645, 266, 674, 789

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 266 are 2 x 7 x 19

Prime factors of 674 are 2 x 337

Prime factors of 789 are 3 x 263

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

Given numbers are 645, 266, 674, 789

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

Apply this formula for all numbers.

Step1:

LCM(645, 266) = 171570

GCD(645, 266) = ( 645 x 266 ) / 171570

= 645 / 266

= 645

Step2:

LCM(1, 674) = 674

GCD(1, 674) = ( 1 x 674 ) / 674

= 1 / 674

= 1

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 645, 266, 674, 789 is 1
