Given numbers are 489, 494, 399, 400

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 494 are 2 x 13 x 19

Prime factors of 399 are 3 x 7 x 19

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 489, 494, 399, 400

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

Apply this formula for all numbers.

Step1:

LCM(489, 494) = 241566

GCD(489, 494) = ( 489 x 494 ) / 241566

= 489 / 494

= 489

Step2:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 489, 494, 399, 400 is 1
