Given numbers are 822, 161, 630, 789

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 161 are 7 x 23

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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 822, 161, 630, 789

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

Apply this formula for all numbers.

Step1:

LCM(822, 161) = 132342

GCD(822, 161) = ( 822 x 161 ) / 132342

= 822 / 161

= 822

Step2:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

Step3:

LCM(1, 789) = 789

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

= 1 / 789

= 1

So, Greatest Common Divisor of 822, 161, 630, 789 is 1
