The list of prime factors of all numbers are

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

Prime factors of 285 are 3 x 5 x 19

Prime factors of 753 are 3 x 251

Prime factors of 755 are 5 x 151

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

Given numbers are 189, 285, 753, 755

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

Apply this formula for all numbers.

Step1:

LCM(189, 285) = 17955

GCD(189, 285) = ( 189 x 285 ) / 17955

= 189 / 285

= 189

Step2:

LCM(3, 753) = 753

GCD(3, 753) = ( 3 x 753 ) / 753

= 3 / 753

= 3

Step3:

LCM(3, 755) = 2265

GCD(3, 755) = ( 3 x 755 ) / 2265

= 3 / 755

= 3

So, Greatest Common Divisor of 189, 285, 753, 755 is 1
