Given numbers are 123, 139, 180, 634

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 139 are 139

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 634 are 2 x 317

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

Given numbers are 123, 139, 180, 634

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

Apply this formula for all numbers.

Step1:

LCM(123, 139) = 17097

GCD(123, 139) = ( 123 x 139 ) / 17097

= 123 / 139

= 123

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 123, 139, 180, 634 is 1
