Given numbers are 189, 530, 529, 505

The list of prime factors of all numbers are

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 530 are 2 x 5 x 53

Prime factors of 529 are 23 x 23

Prime factors of 505 are 5 x 101

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

Given numbers are 189, 530, 529, 505

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

Apply this formula for all numbers.

Step1:

LCM(189, 530) = 100170

GCD(189, 530) = ( 189 x 530 ) / 100170

= 189 / 530

= 189

Step2:

LCM(1, 529) = 529

GCD(1, 529) = ( 1 x 529 ) / 529

= 1 / 529

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 189, 530, 529, 505 is 1
