Given numbers are 168, 455, 268, 489

The list of prime factors of all numbers are

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

Prime factors of 455 are 5 x 7 x 13

Prime factors of 268 are 2 x 2 x 67

Prime factors of 489 are 3 x 163

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

Given numbers are 168, 455, 268, 489

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

Apply this formula for all numbers.

Step1:

LCM(168, 455) = 10920

GCD(168, 455) = ( 168 x 455 ) / 10920

= 168 / 455

= 168

Step2:

LCM(7, 268) = 1876

GCD(7, 268) = ( 7 x 268 ) / 1876

= 7 / 268

= 7

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 168, 455, 268, 489 is 1
