Given numbers are 170, 656, 405, 832

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13

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

Given numbers are 170, 656, 405, 832

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

Apply this formula for all numbers.

Step1:

LCM(170, 656) = 55760

GCD(170, 656) = ( 170 x 656 ) / 55760

= 170 / 656

= 170

Step2:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

Step3:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

So, Greatest Common Divisor of 170, 656, 405, 832 is 1
