Given numbers are 605, 903, 808, 409

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 903 are 3 x 7 x 43

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 409 are 409

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

Given numbers are 605, 903, 808, 409

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

Apply this formula for all numbers.

Step1:

LCM(605, 903) = 546315

GCD(605, 903) = ( 605 x 903 ) / 546315

= 605 / 903

= 605

Step2:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 605, 903, 808, 409 is 1
