Given numbers are 330, 190, 645, 189

The list of prime factors of all numbers are

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 190 are 2 x 5 x 19

Prime factors of 645 are 3 x 5 x 43

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

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

Given numbers are 330, 190, 645, 189

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

Apply this formula for all numbers.

Step1:

LCM(330, 190) = 6270

GCD(330, 190) = ( 330 x 190 ) / 6270

= 330 / 190

= 330

Step2:

LCM(10, 645) = 1290

GCD(10, 645) = ( 10 x 645 ) / 1290

= 10 / 645

= 10

Step3:

LCM(5, 189) = 945

GCD(5, 189) = ( 5 x 189 ) / 945

= 5 / 189

= 5

So, Greatest Common Divisor of 330, 190, 645, 189 is 1
