Given numbers are 408, 788, 166, 255

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 788 are 2 x 2 x 197

Prime factors of 166 are 2 x 83

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 408, 788, 166, 255

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

Apply this formula for all numbers.

Step1:

LCM(408, 788) = 80376

GCD(408, 788) = ( 408 x 788 ) / 80376

= 408 / 788

= 408

Step2:

LCM(4, 166) = 332

GCD(4, 166) = ( 4 x 166 ) / 332

= 4 / 166

= 4

Step3:

LCM(2, 255) = 510

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

= 2 / 255

= 2

So, Greatest Common Divisor of 408, 788, 166, 255 is 1
