Given numbers are 311, 427, 208, 816

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 427 are 7 x 61

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

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

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

Given numbers are 311, 427, 208, 816

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

Apply this formula for all numbers.

Step1:

LCM(311, 427) = 132797

GCD(311, 427) = ( 311 x 427 ) / 132797

= 311 / 427

= 311

Step2:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

Step3:

LCM(1, 816) = 816

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

= 1 / 816

= 1

So, Greatest Common Divisor of 311, 427, 208, 816 is 1
