Given numbers are 289, 240, 404, 630

The list of prime factors of all numbers are

Prime factors of 289 are 17 x 17

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 404 are 2 x 2 x 101

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 289, 240, 404, 630

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

Apply this formula for all numbers.

Step1:

LCM(289, 240) = 69360

GCD(289, 240) = ( 289 x 240 ) / 69360

= 289 / 240

= 289

Step2:

LCM(1, 404) = 404

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

= 1 / 404

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 289, 240, 404, 630 is 1
