Given numbers are 455, 723, 30, 806

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 723 are 3 x 241

Prime factors of 30 are 2 x 3 x 5

Prime factors of 806 are 2 x 13 x 31

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

Given numbers are 455, 723, 30, 806

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

Apply this formula for all numbers.

Step1:

LCM(455, 723) = 328965

GCD(455, 723) = ( 455 x 723 ) / 328965

= 455 / 723

= 455

Step2:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

Step3:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

So, Greatest Common Divisor of 455, 723, 30, 806 is 1
