Given numbers are 563, 756, 171, 255

The list of prime factors of all numbers are

Prime factors of 563 are 563

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 171 are 3 x 3 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 563, 756, 171, 255

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

Apply this formula for all numbers.

Step1:

LCM(563, 756) = 425628

GCD(563, 756) = ( 563 x 756 ) / 425628

= 563 / 756

= 563

Step2:

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

= 1 / 171

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 563, 756, 171, 255 is 1
