How do I find the factors or divisors of the number 161,031,384?

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 161,031,384, 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.

1 161,031,384

Next, we take the number 161,031,384 and divide it by 2.

In this case, 161,031,384 ÷ 2 = 80,515,692

If the quotient is a whole number, then 2 and 80,515,692 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 80,515,692 161,031,384

Now, we try dividing 161,031,384 by 3.

161,031,384 ÷ 3 = 53,677,128

If the quotient is a whole number, then 3 and 53,677,128 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 53,677,128 80,515,692 161,031,384

Let's try dividing by 4.

161,031,384 ÷ 4 = 40,257,846

If the quotient is a whole number, then 4 and 40,257,846 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 40,257,846 53,677,128 80,515,692 161,031,384

We keep dividing by the next largest number, in this case the number 5. If the quotient of 161,031,384 ÷ 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.


What you will end up with is this table:
