How do I find the factors or divisors of the number 400,401,444?

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 400,401,444, 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.

1 400,401,444

Next, we take the number 400,401,444 and divide it by 2.

In this case, 400,401,444 ÷ 2 = 200,200,722

If the quotient is a whole number, then 2 and 200,200,722 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 200,200,722 400,401,444

Now, we try dividing 400,401,444 by 3.

400,401,444 ÷ 3 = 133,467,148

If the quotient is a whole number, then 3 and 133,467,148 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 3 133,467,148 200,200,722 400,401,444

Let's try dividing by 4.

400,401,444 ÷ 4 = 100,100,361

If the quotient is a whole number, then 4 and 100,100,361 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 4 100,100,361 133,467,148 200,200,722 400,401,444

We keep dividing by the next largest number, in this case the number 5. If the quotient of 400,401,444 ÷ 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:

123461233,366,78766,733,574100,100,361133,467,148200,200,722400,401,444

All of the numbers in the table above can be evenly divided into the number 400,401,444.
