Given numbers are 642, 530, 768, 449

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 530 are 2 x 5 x 53

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 449 are 449

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

Given numbers are 642, 530, 768, 449

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

Apply this formula for all numbers.

Step1:

LCM(642, 530) = 170130

GCD(642, 530) = ( 642 x 530 ) / 170130

= 642 / 530

= 642

Step2:

LCM(2, 768) = 768

GCD(2, 768) = ( 2 x 768 ) / 768

= 2 / 768

= 2

Step3:

LCM(2, 449) = 898

GCD(2, 449) = ( 2 x 449 ) / 898

= 2 / 449

= 2

So, Greatest Common Divisor of 642, 530, 768, 449 is 1
