Given numbers are 203, 445, 505, 408

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 445 are 5 x 89

Prime factors of 505 are 5 x 101

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 203, 445, 505, 408

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

Apply this formula for all numbers.

Step1:

LCM(203, 445) = 90335

GCD(203, 445) = ( 203 x 445 ) / 90335

= 203 / 445

= 203

Step2:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

Step3:

LCM(1, 408) = 408

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

= 1 / 408

= 1

So, Greatest Common Divisor of 203, 445, 505, 408 is 1
