Given numbers are 664, 218, 446, 605

The list of prime factors of all numbers are

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 218 are 2 x 109

Prime factors of 446 are 2 x 223

Prime factors of 605 are 5 x 11 x 11

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

Given numbers are 664, 218, 446, 605

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

Apply this formula for all numbers.

Step1:

LCM(664, 218) = 72376

GCD(664, 218) = ( 664 x 218 ) / 72376

= 664 / 218

= 664

Step2:

LCM(2, 446) = 446

GCD(2, 446) = ( 2 x 446 ) / 446

= 2 / 446

= 2

Step3:

LCM(2, 605) = 1210

GCD(2, 605) = ( 2 x 605 ) / 1210

= 2 / 605

= 2

So, Greatest Common Divisor of 664, 218, 446, 605 is 1
