Given numbers are 438, 530, 509, 671

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 530 are 2 x 5 x 53

Prime factors of 509 are 509

Prime factors of 671 are 11 x 61

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

Given numbers are 438, 530, 509, 671

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

Apply this formula for all numbers.

Step1:

LCM(438, 530) = 116070

GCD(438, 530) = ( 438 x 530 ) / 116070

= 438 / 530

= 438

Step2:

LCM(2, 509) = 1018

GCD(2, 509) = ( 2 x 509 ) / 1018

= 2 / 509

= 2

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 438, 530, 509, 671 is 1
