Given numbers are 118, 855, 990, 231

The list of prime factors of all numbers are

Prime factors of 118 are 2 x 59

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 118, 855, 990, 231

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

Apply this formula for all numbers.

Step1:

LCM(118, 855) = 100890

GCD(118, 855) = ( 118 x 855 ) / 100890

= 118 / 855

= 118

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 118, 855, 990, 231 is 1
