Given numbers are 561, 485, 406, 936

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 485 are 5 x 97

Prime factors of 406 are 2 x 7 x 29

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

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

Given numbers are 561, 485, 406, 936

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

Apply this formula for all numbers.

Step1:

LCM(561, 485) = 272085

GCD(561, 485) = ( 561 x 485 ) / 272085

= 561 / 485

= 561

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

So, Greatest Common Divisor of 561, 485, 406, 936 is 1
