Given numbers are 605, 442, 318, 408

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 442 are 2 x 13 x 17

Prime factors of 318 are 2 x 3 x 53

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 605, 442, 318, 408

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

Apply this formula for all numbers.

Step1:

LCM(605, 442) = 267410

GCD(605, 442) = ( 605 x 442 ) / 267410

= 605 / 442

= 605

Step2:

LCM(1, 318) = 318

GCD(1, 318) = ( 1 x 318 ) / 318

= 1 / 318

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 605, 442, 318, 408 is 1
