Given numbers are 816, 320, 187, 905

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 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 187 are 11 x 17

Prime factors of 905 are 5 x 181

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

Given numbers are 816, 320, 187, 905

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

Apply this formula for all numbers.

Step1:

LCM(816, 320) = 16320

GCD(816, 320) = ( 816 x 320 ) / 16320

= 816 / 320

= 816

Step2:

LCM(16, 187) = 2992

GCD(16, 187) = ( 16 x 187 ) / 2992

= 16 / 187

= 16

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 816, 320, 187, 905 is 1
