Given numbers are 445, 732, 168, 489

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 732 are 2 x 2 x 3 x 61

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

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 445, 732, 168, 489

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

Apply this formula for all numbers.

Step1:

LCM(445, 732) = 325740

GCD(445, 732) = ( 445 x 732 ) / 325740

= 445 / 732

= 445

Step2:

LCM(1, 168) = 168

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

= 1 / 168

= 1

Step3:

LCM(1, 489) = 489

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

= 1 / 489

= 1

So, Greatest Common Divisor of 445, 732, 168, 489 is 1
