Given numbers are 530, 255, 740, 189

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 255 are 3 x 5 x 17

Prime factors of 740 are 2 x 2 x 5 x 37

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 530, 255, 740, 189

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

Apply this formula for all numbers.

Step1:

LCM(530, 255) = 27030

GCD(530, 255) = ( 530 x 255 ) / 27030

= 530 / 255

= 530

Step2:

LCM(5, 740) = 740

GCD(5, 740) = ( 5 x 740 ) / 740

= 5 / 740

= 5

Step3:

LCM(5, 189) = 945

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

= 5 / 189

= 5

So, Greatest Common Divisor of 530, 255, 740, 189 is 1
