Given numbers are 663, 521, 207, 404

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 521 are 521

Prime factors of 207 are 3 x 3 x 23

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 663, 521, 207, 404

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

Apply this formula for all numbers.

Step1:

LCM(663, 521) = 345423

GCD(663, 521) = ( 663 x 521 ) / 345423

= 663 / 521

= 663

Step2:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 663, 521, 207, 404 is 1
