Given numbers are 405, 170, 496, 397

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 170 are 2 x 5 x 17

Prime factors of 496 are 2 x 2 x 2 x 2 x 31

Prime factors of 397 are 397

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

Given numbers are 405, 170, 496, 397

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

Apply this formula for all numbers.

Step1:

LCM(405, 170) = 13770

GCD(405, 170) = ( 405 x 170 ) / 13770

= 405 / 170

= 405

Step2:

LCM(5, 496) = 2480

GCD(5, 496) = ( 5 x 496 ) / 2480

= 5 / 496

= 5

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 405, 170, 496, 397 is 1
