Given numbers are 118, 687, 290, 810

The list of prime factors of all numbers are

Prime factors of 118 are 2 x 59

Prime factors of 687 are 3 x 229

Prime factors of 290 are 2 x 5 x 29

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 118, 687, 290, 810

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

Apply this formula for all numbers.

Step1:

LCM(118, 687) = 81066

GCD(118, 687) = ( 118 x 687 ) / 81066

= 118 / 687

= 118

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

Step3:

LCM(1, 810) = 810

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

= 1 / 810

= 1

So, Greatest Common Divisor of 118, 687, 290, 810 is 1
