Given numbers are 480, 635, 255, 489

The list of prime factors of all numbers are

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 635 are 5 x 127

Prime factors of 255 are 3 x 5 x 17

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 480, 635, 255, 489

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

Apply this formula for all numbers.

Step1:

LCM(480, 635) = 60960

GCD(480, 635) = ( 480 x 635 ) / 60960

= 480 / 635

= 480

Step2:

LCM(5, 255) = 255

GCD(5, 255) = ( 5 x 255 ) / 255

= 5 / 255

= 5

Step3:

LCM(5, 489) = 2445

GCD(5, 489) = ( 5 x 489 ) / 2445

= 5 / 489

= 5

So, Greatest Common Divisor of 480, 635, 255, 489 is 1
