Given numbers are 405, 397, 696, 931

The list of prime factors of all numbers are

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

Prime factors of 397 are 397

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

Prime factors of 931 are 7 x 7 x 19

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

Given numbers are 405, 397, 696, 931

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

Apply this formula for all numbers.

Step1:

LCM(405, 397) = 160785

GCD(405, 397) = ( 405 x 397 ) / 160785

= 405 / 397

= 405

Step2:

LCM(1, 696) = 696

GCD(1, 696) = ( 1 x 696 ) / 696

= 1 / 696

= 1

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 405, 397, 696, 931 is 1
