Given numbers are 643, 570, 396, 581

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 581 are 7 x 83

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

Given numbers are 643, 570, 396, 581

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

Apply this formula for all numbers.

Step1:

LCM(643, 570) = 366510

GCD(643, 570) = ( 643 x 570 ) / 366510

= 643 / 570

= 643

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 643, 570, 396, 581 is 1
