Given numbers are 489, 828, 650, 123

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 123 are 3 x 41

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

Given numbers are 489, 828, 650, 123

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

Apply this formula for all numbers.

Step1:

LCM(489, 828) = 134964

GCD(489, 828) = ( 489 x 828 ) / 134964

= 489 / 828

= 489

Step2:

LCM(3, 650) = 1950

GCD(3, 650) = ( 3 x 650 ) / 1950

= 3 / 650

= 3

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 489, 828, 650, 123 is 1
