Given numbers are 644, 530, 357, 323

The list of prime factors of all numbers are

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

Prime factors of 530 are 2 x 5 x 53

Prime factors of 357 are 3 x 7 x 17

Prime factors of 323 are 17 x 19

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

Given numbers are 644, 530, 357, 323

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

Apply this formula for all numbers.

Step1:

LCM(644, 530) = 170660

GCD(644, 530) = ( 644 x 530 ) / 170660

= 644 / 530

= 644

Step2:

LCM(2, 357) = 714

GCD(2, 357) = ( 2 x 357 ) / 714

= 2 / 357

= 2

Step3:

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

= 1 / 323

= 1

So, Greatest Common Divisor of 644, 530, 357, 323 is 1
