Given numbers are 126, 111, 321, 823

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 111 are 3 x 37

Prime factors of 321 are 3 x 107

Prime factors of 823 are 823

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

Given numbers are 126, 111, 321, 823

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

Apply this formula for all numbers.

Step1:

LCM(126, 111) = 4662

GCD(126, 111) = ( 126 x 111 ) / 4662

= 126 / 111

= 126

Step2:

LCM(3, 321) = 321

GCD(3, 321) = ( 3 x 321 ) / 321

= 3 / 321

= 3

Step3:

LCM(3, 823) = 2469

GCD(3, 823) = ( 3 x 823 ) / 2469

= 3 / 823

= 3

So, Greatest Common Divisor of 126, 111, 321, 823 is 1
