Given numbers are 455, 867, 168, 208

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 867 are 3 x 17 x 17

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

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

Given numbers are 455, 867, 168, 208

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

Apply this formula for all numbers.

Step1:

LCM(455, 867) = 394485

GCD(455, 867) = ( 455 x 867 ) / 394485

= 455 / 867

= 455

Step2:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

Step3:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 455, 867, 168, 208 is 1
