Given numbers are 720, 399, 656, 239

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 399 are 3 x 7 x 19

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 239 are 239

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

Given numbers are 720, 399, 656, 239

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

Apply this formula for all numbers.

Step1:

LCM(720, 399) = 95760

GCD(720, 399) = ( 720 x 399 ) / 95760

= 720 / 399

= 720

Step2:

LCM(3, 656) = 1968

GCD(3, 656) = ( 3 x 656 ) / 1968

= 3 / 656

= 3

Step3:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

So, Greatest Common Divisor of 720, 399, 656, 239 is 1
