Given numbers are 288, 221, 607, 420

The list of prime factors of all numbers are

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 221 are 13 x 17

Prime factors of 607 are 607

Prime factors of 420 are 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 288, 221, 607, 420

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

Apply this formula for all numbers.

Step1:

LCM(288, 221) = 63648

GCD(288, 221) = ( 288 x 221 ) / 63648

= 288 / 221

= 288

Step2:

LCM(1, 607) = 607

GCD(1, 607) = ( 1 x 607 ) / 607

= 1 / 607

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 288, 221, 607, 420 is 1
