The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.
The greatest common factor of 990 and 999 is 9
There is not a greatest common factor of a single number, such as 999, because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. The factors of 999 are 1, 3, 9, 27, 37, 111, 333, and 999. The prime factors of 999 are 3, 3, 3, and 37. Examples: The greatest common factor of 54 and 999 is 27. The greatest common factor of 185 and 999 is 37. The greatest common factor of 999 and 1001 is 1.

Those four numbers are all whole numbers.
You would say to yourself:-- If it has to be divisible by 5 and 9, then it's divisible by 45.-- The biggest 3-digit number is 999.-- 999 divided by 45 is 22.2-- So if I multiply 45 by only 22 and leave off the 0.2,I'll get the biggest one that's less than 999.-- 45 x 22 = 990 .
No 999,990 is not an odd number
