Given numbers are 281, 420, 816, 519

The list of prime factors of all numbers are

Prime factors of 281 are 281

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Prime factors of 519 are 3 x 173

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

Given numbers are 281, 420, 816, 519

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

Apply this formula for all numbers.

Step1:

LCM(281, 420) = 118020

GCD(281, 420) = ( 281 x 420 ) / 118020

= 281 / 420

= 281

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

= 1 / 519

= 1

So, Greatest Common Divisor of 281, 420, 816, 519 is 1
