Given numbers are 408, 664, 461, 561

The list of prime factors of all numbers are

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

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

Prime factors of 461 are 461

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 408, 664, 461, 561

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

Apply this formula for all numbers.

Step1:

LCM(408, 664) = 33864

GCD(408, 664) = ( 408 x 664 ) / 33864

= 408 / 664

= 408

Step2:

LCM(8, 461) = 3688

GCD(8, 461) = ( 8 x 461 ) / 3688

= 8 / 461

= 8

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 408, 664, 461, 561 is 1
