Given numbers are 612, 645, 130, 189

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 645 are 3 x 5 x 43

Prime factors of 130 are 2 x 5 x 13

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 612, 645, 130, 189

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

Apply this formula for all numbers.

Step1:

LCM(612, 645) = 131580

GCD(612, 645) = ( 612 x 645 ) / 131580

= 612 / 645

= 612

Step2:

LCM(3, 130) = 390

GCD(3, 130) = ( 3 x 130 ) / 390

= 3 / 130

= 3

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 612, 645, 130, 189 is 1
