Given numbers are 485, 206, 324, 720

The list of prime factors of all numbers are

Prime factors of 485 are 5 x 97

Prime factors of 206 are 2 x 103

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

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

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

Given numbers are 485, 206, 324, 720

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

Apply this formula for all numbers.

Step1:

LCM(485, 206) = 99910

GCD(485, 206) = ( 485 x 206 ) / 99910

= 485 / 206

= 485

Step2:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 485, 206, 324, 720 is 1
