Given numbers are 511, 253, 720, 393

The list of prime factors of all numbers are

Prime factors of 511 are 7 x 73

Prime factors of 253 are 11 x 23

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

Prime factors of 393 are 3 x 131

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

Given numbers are 511, 253, 720, 393

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

Apply this formula for all numbers.

Step1:

LCM(511, 253) = 129283

GCD(511, 253) = ( 511 x 253 ) / 129283

= 511 / 253

= 511

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 511, 253, 720, 393 is 1
