Given numbers are 843, 405, 563, 957

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

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

Prime factors of 563 are 563

Prime factors of 957 are 3 x 11 x 29

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

Given numbers are 843, 405, 563, 957

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

Apply this formula for all numbers.

Step1:

LCM(843, 405) = 113805

GCD(843, 405) = ( 843 x 405 ) / 113805

= 843 / 405

= 843

Step2:

LCM(3, 563) = 1689

GCD(3, 563) = ( 3 x 563 ) / 1689

= 3 / 563

= 3

Step3:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

So, Greatest Common Divisor of 843, 405, 563, 957 is 1
