Given numbers are 606, 656, 443, 420

The list of prime factors of all numbers are

Prime factors of 606 are 2 x 3 x 101

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 443 are 443

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

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

Given numbers are 606, 656, 443, 420

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

Apply this formula for all numbers.

Step1:

LCM(606, 656) = 198768

GCD(606, 656) = ( 606 x 656 ) / 198768

= 606 / 656

= 606

Step2:

LCM(2, 443) = 886

GCD(2, 443) = ( 2 x 443 ) / 886

= 2 / 443

= 2

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 606, 656, 443, 420 is 1
