How do I find the factors or divisors of the number 15,558,948?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 15,558,948, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 15,558,948

Next, we take the number 15,558,948 and divide it by 2.

In this case, 15,558,948 ÷ 2 = 7,779,474

If the quotient is a whole number, then 2 and 7,779,474 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 7,779,474 15,558,948

Now, we try dividing 15,558,948 by 3.

15,558,948 ÷ 3 = 5,186,316

If the quotient is a whole number, then 3 and 5,186,316 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 5,186,316 7,779,474 15,558,948

Let's try dividing by 4.

15,558,948 ÷ 4 = 3,889,737

If the quotient is a whole number, then 4 and 3,889,737 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 4 3,889,737 5,186,316 7,779,474 15,558,948

We keep dividing by the next largest number, in this case the number 5. If the quotient of 15,558,948 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.
