Given numbers are 622, 420, 653, 789

The list of prime factors of all numbers are

Prime factors of 622 are 2 x 311

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 653 are 653

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 622, 420, 653, 789

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

Apply this formula for all numbers.

Step1:

LCM(622, 420) = 130620

GCD(622, 420) = ( 622 x 420 ) / 130620

= 622 / 420

= 622

Step2:

LCM(2, 653) = 1306

GCD(2, 653) = ( 2 x 653 ) / 1306

= 2 / 653

= 2

Step3:

LCM(1, 789) = 789

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

= 1 / 789

= 1

So, Greatest Common Divisor of 622, 420, 653, 789 is 1
