Given numbers are 123, 330, 133, 320

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 133 are 7 x 19

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 123, 330, 133, 320

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

Apply this formula for all numbers.

Step1:

LCM(123, 330) = 13530

GCD(123, 330) = ( 123 x 330 ) / 13530

= 123 / 330

= 123

Step2:

LCM(3, 133) = 399

GCD(3, 133) = ( 3 x 133 ) / 399

= 3 / 133

= 3

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 123, 330, 133, 320 is 1
