Given numbers are 455, 738, 560, 489

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 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 455, 738, 560, 489

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

Apply this formula for all numbers.

Step1:

LCM(455, 738) = 335790

GCD(455, 738) = ( 455 x 738 ) / 335790

= 455 / 738

= 455

Step2:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

Step3:

LCM(1, 489) = 489

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

= 1 / 489

= 1

So, Greatest Common Divisor of 455, 738, 560, 489 is 1
