Given numbers are 206, 878, 255, 450

The list of prime factors of all numbers are

Prime factors of 206 are 2 x 103

Prime factors of 878 are 2 x 439

Prime factors of 255 are 3 x 5 x 17

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 206, 878, 255, 450

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

Apply this formula for all numbers.

Step1:

LCM(206, 878) = 90434

GCD(206, 878) = ( 206 x 878 ) / 90434

= 206 / 878

= 206

Step2:

LCM(2, 255) = 510

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

= 2 / 255

= 2

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 206, 878, 255, 450 is 1
