Given numbers are 123, 245, 243, 867

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 245 are 5 x 7 x 7

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 867 are 3 x 17 x 17

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

Given numbers are 123, 245, 243, 867

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

Apply this formula for all numbers.

Step1:

LCM(123, 245) = 30135

GCD(123, 245) = ( 123 x 245 ) / 30135

= 123 / 245

= 123

Step2:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

Step3:

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

= 1 / 867

= 1

So, Greatest Common Divisor of 123, 245, 243, 867 is 1
