Given numbers are 530, 638, 865, 511

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 638 are 2 x 11 x 29

Prime factors of 865 are 5 x 173

Prime factors of 511 are 7 x 73

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

Given numbers are 530, 638, 865, 511

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

Apply this formula for all numbers.

Step1:

LCM(530, 638) = 169070

GCD(530, 638) = ( 530 x 638 ) / 169070

= 530 / 638

= 530

Step2:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 530, 638, 865, 511 is 1
