Given numbers are 816, 818, 211, 455

The list of prime factors of all numbers are

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 818 are 2 x 409

Prime factors of 211 are 211

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 816, 818, 211, 455

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

Apply this formula for all numbers.

Step1:

LCM(816, 818) = 333744

GCD(816, 818) = ( 816 x 818 ) / 333744

= 816 / 818

= 816

Step2:

LCM(2, 211) = 422

GCD(2, 211) = ( 2 x 211 ) / 422

= 2 / 211

= 2

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 816, 818, 211, 455 is 1
