What are the set of numbers that when multiplied will make a certain number?
They are that number's factors.If its the complete set of the smallest such numbers, they are the prime factors.What's the difference? 4 and 15 are factors of 60: 4 x 15 = 60.But the prime factors of 60 are 2 x 2 x 3 x 5. (Note that these are all prime numbers, which is where the term comes from.)By multiplying the prime factors in different combinations -- such as 2 x (2 x 3) x 5 -- we can come up with all the possible combinations which lead to the original number.Also note that the only prime factor of a prime number is itself. Some teachers will tell you that the factors of a prime number are itself and 1, which is also true: 1 (known as unity) is special in that every number, when divided by it, remains the same. But 1 itself is not considered a prime number.
How many times will the number 4 come up if you toss a 6 sided die 30 times?
The actual number of times 4 comes up is impossible to find, but the expected value of 4 coming up if you toss a 6-sided die 30 times is 5 times.

How come you can take the square root of a positive number but not a negative?
The square root of a number has two roots; by definition the answer multiplied by itself is the square root of the result. Two numbers multiplied by themselves always ends up positive; for example sqrt(36) = +6 or -6; +6 x +6 = +36 and -6 x -6 = +36. The sqrt of a negative number is imaginary and is a multiple of the imaginary number, i.
When driving wipers come on by itself why?

What is the least common multiple of 3 and 7 and 5?
The least common multiple of 3, 5, and 7 is 105.This is the first number that each of these numbers have in common when finding the multiples of each number. You begin by taking each number and multiplying the number by 1, 2, 3, 4, 5, etc. until you come up with a number that is common to each of the numbers (3,5 and 7). In this case, the first number that the three numbers had in common happened to be 105. The number 3 had to be multiplied 35 times (35x3=105); The number 5 had to be multiplied 21 times (21x5=105); and the number 7 had to be multiplied 15 times to have a number in common with the other two numbers (15x7=105).
