Given numbers are 816, 815, 581, 554

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 815 are 5 x 163

Prime factors of 581 are 7 x 83

Prime factors of 554 are 2 x 277

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

Given numbers are 816, 815, 581, 554

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

Apply this formula for all numbers.

Step1:

LCM(816, 815) = 665040

GCD(816, 815) = ( 816 x 815 ) / 665040

= 816 / 815

= 816

Step2:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 816, 815, 581, 554 is 1
