Given numbers are 831, 551, 208, 810

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 551 are 19 x 29

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

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 831, 551, 208, 810

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

Apply this formula for all numbers.

Step1:

LCM(831, 551) = 457881

GCD(831, 551) = ( 831 x 551 ) / 457881

= 831 / 551

= 831

Step2:

LCM(1, 208) = 208

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

= 1 / 208

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 831, 551, 208, 810 is 1
