Given numbers are 720, 396, 965, 398

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 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 965 are 5 x 193

Prime factors of 398 are 2 x 199

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

Given numbers are 720, 396, 965, 398

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

Apply this formula for all numbers.

Step1:

LCM(720, 396) = 7920

GCD(720, 396) = ( 720 x 396 ) / 7920

= 720 / 396

= 720

Step2:

LCM(36, 965) = 34740

GCD(36, 965) = ( 36 x 965 ) / 34740

= 36 / 965

= 36

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 720, 396, 965, 398 is 1
