Given numbers are 255, 410, 678, 408

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 410 are 2 x 5 x 41

Prime factors of 678 are 2 x 3 x 113

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

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

Given numbers are 255, 410, 678, 408

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

Apply this formula for all numbers.

Step1:

LCM(255, 410) = 20910

GCD(255, 410) = ( 255 x 410 ) / 20910

= 255 / 410

= 255

Step2:

LCM(5, 678) = 3390

GCD(5, 678) = ( 5 x 678 ) / 3390

= 5 / 678

= 5

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 255, 410, 678, 408 is 1
