Given numbers are 489, 810, 644, 115

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 115 are 5 x 23

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

Given numbers are 489, 810, 644, 115

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

Apply this formula for all numbers.

Step1:

LCM(489, 810) = 132030

GCD(489, 810) = ( 489 x 810 ) / 132030

= 489 / 810

= 489

Step2:

LCM(3, 644) = 1932

GCD(3, 644) = ( 3 x 644 ) / 1932

= 3 / 644

= 3

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 489, 810, 644, 115 is 1
