Given numbers are 720, 565, 321, 487

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 565 are 5 x 113

Prime factors of 321 are 3 x 107

Prime factors of 487 are 487

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

Given numbers are 720, 565, 321, 487

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

Apply this formula for all numbers.

Step1:

LCM(720, 565) = 81360

GCD(720, 565) = ( 720 x 565 ) / 81360

= 720 / 565

= 720

Step2:

LCM(5, 321) = 1605

GCD(5, 321) = ( 5 x 321 ) / 1605

= 5 / 321

= 5

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 720, 565, 321, 487 is 1
