Given numbers are 530, 543, 390, 392

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 543 are 3 x 181

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 530, 543, 390, 392

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

Apply this formula for all numbers.

Step1:

LCM(530, 543) = 287790

GCD(530, 543) = ( 530 x 543 ) / 287790

= 530 / 543

= 530

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 530, 543, 390, 392 is 1
