Given numbers are 817, 530, 644, 336

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 530 are 2 x 5 x 53

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 817, 530, 644, 336

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

Apply this formula for all numbers.

Step1:

LCM(817, 530) = 433010

GCD(817, 530) = ( 817 x 530 ) / 433010

= 817 / 530

= 817

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 336) = 336

GCD(1, 336) = ( 1 x 336 ) / 336

= 1 / 336

= 1

So, Greatest Common Divisor of 817, 530, 644, 336 is 1
