Given numbers are 123, 624, 130, 430

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 130 are 2 x 5 x 13

Prime factors of 430 are 2 x 5 x 43

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

Given numbers are 123, 624, 130, 430

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

Apply this formula for all numbers.

Step1:

LCM(123, 624) = 25584

GCD(123, 624) = ( 123 x 624 ) / 25584

= 123 / 624

= 123

Step2:

LCM(3, 130) = 390

GCD(3, 130) = ( 3 x 130 ) / 390

= 3 / 130

= 3

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 123, 624, 130, 430 is 1
