Given numbers are 387, 633, 420, 568

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 633 are 3 x 211

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

Prime factors of 568 are 2 x 2 x 2 x 71

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

Given numbers are 387, 633, 420, 568

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

Apply this formula for all numbers.

Step1:

LCM(387, 633) = 81657

GCD(387, 633) = ( 387 x 633 ) / 81657

= 387 / 633

= 387

Step2:

LCM(3, 420) = 420

GCD(3, 420) = ( 3 x 420 ) / 420

= 3 / 420

= 3

Step3:

LCM(3, 568) = 1704

GCD(3, 568) = ( 3 x 568 ) / 1704

= 3 / 568

= 3

So, Greatest Common Divisor of 387, 633, 420, 568 is 1
