Given numbers are 530, 285, 387, 444

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 285 are 3 x 5 x 19

Prime factors of 387 are 3 x 3 x 43

Prime factors of 444 are 2 x 2 x 3 x 37

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

Given numbers are 530, 285, 387, 444

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

Apply this formula for all numbers.

Step1:

LCM(530, 285) = 30210

GCD(530, 285) = ( 530 x 285 ) / 30210

= 530 / 285

= 530

Step2:

LCM(5, 387) = 1935

GCD(5, 387) = ( 5 x 387 ) / 1935

= 5 / 387

= 5

Step3:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

So, Greatest Common Divisor of 530, 285, 387, 444 is 1
