Given numbers are 170, 290, 457

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 290 are 2 x 5 x 29

Prime factors of 457 are 457

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

Given numbers are 170, 290, 457

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

Apply this formula for all numbers.

Step1:

LCM(170, 290) = 4930

GCD(170, 290) = ( 170 x 290 ) / 4930

= 170 / 290

= 170

Step2:

LCM(10, 457) = 4570

GCD(10, 457) = ( 10 x 457 ) / 4570

= 10 / 457

= 10

So, Greatest Common Divisor of 170, 290, 457 is 1
