Given numbers are 638, 360, 423, 489

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 423 are 3 x 3 x 47

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 638, 360, 423, 489

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

Apply this formula for all numbers.

Step1:

LCM(638, 360) = 114840

GCD(638, 360) = ( 638 x 360 ) / 114840

= 638 / 360

= 638

Step2:

LCM(2, 423) = 846

GCD(2, 423) = ( 2 x 423 ) / 846

= 2 / 423

= 2

Step3:

LCM(1, 489) = 489

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

= 1 / 489

= 1

So, Greatest Common Divisor of 638, 360, 423, 489 is 1
