2310 has all of those as factors.

All composite numbers have more than two factors. The smallest such number is 4, which is equal to 2 x 2. 4 has three factors: 1, 2, and 4.
What is the least common multiple of a set of numbers?
It is the smallest number that is a multiple of all the numbers in the set. Or to put it another way, it is the smallest number divisible by all the numbers in the set.

16 if the prime factors don't have to be distinct. 210 if they do.
What is does the least common factor of a group of numbers mean?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. The smallest of these is known as the least common factor. Since 1 is a common factor of every set of integers, the least common factor of any set of integers is 1.
Do all numbers have factors?
Yes. 1 and the number itself are factors of all numbers.

If the sum of all a number's factors (factors that are smaller than the number itself) is equal to the number itself, the number is said to be "perfect". For example, the factors of 6 (excluding 6 itself) are 1, 2, and 3; and the sum of these numbers is exactly 6. The smallest perfect numbers are 6, 28, 496, 8128. It isn't known whether the set of perfect numbers is finite or infinite. Also, it isn't known whether there are any odd perfect number; all known perfect numbers are even.
