Given numbers are 123, 166, 130, 480

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 166 are 2 x 83

Prime factors of 130 are 2 x 5 x 13

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 123, 166, 130, 480

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

Apply this formula for all numbers.

Step1:

LCM(123, 166) = 20418

GCD(123, 166) = ( 123 x 166 ) / 20418

= 123 / 166

= 123

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 123, 166, 130, 480 is 1
