Given numbers are 129, 446, 430, 442

The list of prime factors of all numbers are

Prime factors of 129 are 3 x 43

Prime factors of 446 are 2 x 223

Prime factors of 430 are 2 x 5 x 43

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 129, 446, 430, 442

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

Apply this formula for all numbers.

Step1:

LCM(129, 446) = 57534

GCD(129, 446) = ( 129 x 446 ) / 57534

= 129 / 446

= 129

Step2:

LCM(1, 430) = 430

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

= 1 / 430

= 1

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 129, 446, 430, 442 is 1
