Given numbers are 561, 405, 882, 401

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

Prime factors of 401 are 401

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

Given numbers are 561, 405, 882, 401

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

Apply this formula for all numbers.

Step1:

LCM(561, 405) = 75735

GCD(561, 405) = ( 561 x 405 ) / 75735

= 561 / 405

= 561

Step2:

LCM(3, 882) = 882

GCD(3, 882) = ( 3 x 882 ) / 882

= 3 / 882

= 3

Step3:

LCM(3, 401) = 1203

GCD(3, 401) = ( 3 x 401 ) / 1203

= 3 / 401

= 3

So, Greatest Common Divisor of 561, 405, 882, 401 is 1
