Given numbers are 170, 255, 520, 554

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 255 are 3 x 5 x 17

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 554 are 2 x 277

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

Given numbers are 170, 255, 520, 554

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

Apply this formula for all numbers.

Step1:

LCM(170, 255) = 510

GCD(170, 255) = ( 170 x 255 ) / 510

= 170 / 255

= 170

Step2:

LCM(85, 520) = 8840

GCD(85, 520) = ( 85 x 520 ) / 8840

= 85 / 520

= 85

Step3:

LCM(5, 554) = 2770

GCD(5, 554) = ( 5 x 554 ) / 2770

= 5 / 554

= 5

So, Greatest Common Divisor of 170, 255, 520, 554 is 1
