Given numbers are 489, 473, 250, 840

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 473 are 11 x 43

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 489, 473, 250, 840

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

Apply this formula for all numbers.

Step1:

LCM(489, 473) = 231297

GCD(489, 473) = ( 489 x 473 ) / 231297

= 489 / 473

= 489

Step2:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 489, 473, 250, 840 is 1
