Given numbers are 581, 420, 587, 396

The list of prime factors of all numbers are

Prime factors of 581 are 7 x 83

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 587 are 587

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

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

Given numbers are 581, 420, 587, 396

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

Apply this formula for all numbers.

Step1:

LCM(581, 420) = 34860

GCD(581, 420) = ( 581 x 420 ) / 34860

= 581 / 420

= 581

Step2:

LCM(7, 587) = 4109

GCD(7, 587) = ( 7 x 587 ) / 4109

= 7 / 587

= 7

Step3:

LCM(1, 396) = 396

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

= 1 / 396

= 1

So, Greatest Common Divisor of 581, 420, 587, 396 is 1
