Given numbers are 485, 818, 720, 432

The list of prime factors of all numbers are

Prime factors of 485 are 5 x 97

Prime factors of 818 are 2 x 409

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

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 485, 818, 720, 432

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

Apply this formula for all numbers.

Step1:

LCM(485, 818) = 396730

GCD(485, 818) = ( 485 x 818 ) / 396730

= 485 / 818

= 485

Step2:

LCM(1, 720) = 720

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

= 1 / 720

= 1

Step3:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

So, Greatest Common Divisor of 485, 818, 720, 432 is 1
