Given numbers are 170, 806, 254, 643

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 806 are 2 x 13 x 31

Prime factors of 254 are 2 x 127

Prime factors of 643 are 643

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

Given numbers are 170, 806, 254, 643

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

Apply this formula for all numbers.

Step1:

LCM(170, 806) = 68510

GCD(170, 806) = ( 170 x 806 ) / 68510

= 170 / 806

= 170

Step2:

LCM(2, 254) = 254

GCD(2, 254) = ( 2 x 254 ) / 254

= 2 / 254

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 170, 806, 254, 643 is 1
