Given numbers are 355, 561, 447, 408

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 561 are 3 x 11 x 17

Prime factors of 447 are 3 x 149

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 355, 561, 447, 408

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

Apply this formula for all numbers.

Step1:

LCM(355, 561) = 199155

GCD(355, 561) = ( 355 x 561 ) / 199155

= 355 / 561

= 355

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 408) = 408

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

= 1 / 408

= 1

So, Greatest Common Divisor of 355, 561, 447, 408 is 1
