Given numbers are 170, 754, 38, 255

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 754 are 2 x 13 x 29

Prime factors of 38 are 2 x 19

Prime factors of 255 are 3 x 5 x 17

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

Given numbers are 170, 754, 38, 255

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

Apply this formula for all numbers.

Step1:

LCM(170, 754) = 64090

GCD(170, 754) = ( 170 x 754 ) / 64090

= 170 / 754

= 170

Step2:

LCM(2, 38) = 38

GCD(2, 38) = ( 2 x 38 ) / 38

= 2 / 38

= 2

Step3:

LCM(2, 255) = 510

GCD(2, 255) = ( 2 x 255 ) / 510

= 2 / 255

= 2

So, Greatest Common Divisor of 170, 754, 38, 255 is 1
