Given numbers are 205, 189, 660, 509

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

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

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 509 are 509

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

Given numbers are 205, 189, 660, 509

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

Apply this formula for all numbers.

Step1:

LCM(205, 189) = 38745

GCD(205, 189) = ( 205 x 189 ) / 38745

= 205 / 189

= 205

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 205, 189, 660, 509 is 1
