If N is the number, and f is the number that you want to test as a possible factor, then first of all:
test N > f (this must be true, the factors are always smaller in magnitude)
next perform N ÷ f (N divided by f). If the quotient (answer to a division problem) is a whole number with no remainder or fractional part, then f is a factor of N.
If the quotient is not a whole number (meaning there is a remainder), then f is not a factor.

How can you test to determine if a factor is a factor of another number?
Divide the factor into the number. If the answer is a whole number, the factor is a factor.
What are divisibility rules used for in real life?
You use divisibility rules t determine whether a particular number is (or is not) a factor of another number. If it is a factor, you can reduce the numbers involved to smaller numbers.You might want to find factors to simplify fractions or to add or subtract factions.
How do you find the 12th prime number using c?
To keep it simple: Write a main loop that goes through all the numbers, starting with 2, and incrementing one at a time. Determine whether each number is a prime number. If it is, increment a counter. To determine whether each number is a prime number, either use an inner loop, or a separate function. Test divisibility of the number "n" by every number from 2 to n-1. If you find a factor, then it is not a prime number. Note that you can test divisibility by using the "%" operator. For example: if (number % factor == 0) // number is divisible by factor else // it isn't
A number is divisible by another number when?
When it is a factor of that number
If one number is a factor of another number will the greatest common factor will be the lesser number. explain?
If one number is a factor of another number, the greatest common factor will be the lesser number. Example: 3 and 9 3 is a factor of 9 3 is a factor of 3 There can be no higher factor of a number than the number itself. Therefore, the GCF of 3 and 9 is 3.
How can you test to determine whether a number is a factor of another numberr?
Divide the smaller number into the bigger number. If the answer comes out even with no remainder, it's a factor.
How can you test to determine whether a number is a factor of another number?
Divide the larger number by the smaller. If the result has no remainder (no decimal) then the smaller number is a factor of the larger.
How can you test to determine if a factor is a factor of another number?
Divide the factor into the number. If the answer is a whole number, the factor is a factor.
How can you determine if a number is a factor of another number?
If a number can be evenly divided by another number, the smaller number is a factor of the larger number.
How can you determine whether one number is a factor of another?
Divide the smaller into the larger. If the quotient is an integer, the smaller is a factor of the larger.
How can you use the prime factorization to determine whether 35 is a factor of the number?
If the prime factorization contains a 5 and a 7, 35 is a factor.
A number that is multiplied by another number to get a product?
This is called a factor. Factors, by definition, are numbers you can multiply together to get another number, or a product.

How can you test t determine whether a number is a factor of a number?
it's simple, you divide the potential factor by the original number.For example, if I wanted to find out if 12 was a factor of 36;36/12= 3Because this number is an integer and not a decimal we know that in fact, 12 is a factor of 36.I hope that helped :)

How can you determine whether a counting number is a composite number?
Start looking for factors; you already know that 1 is a factor, and that the number itself is a second factor (unless the number is 1). As soon as you find a factor that is neither 1 nor the number itself, the number is composite. If you find exactly two factors, the number is prime. If the number has only one factor, the number is 1, which is neither prime nor composite.
Is a common factor a number that goes into another number without having any remainders?
No, that's just a factor. A common factor is when that factor is also a factor of another number.
