How do I find the factors or divisors of the number 73,401,240?

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 73,401,240, 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 73,401,240

Next, we take the number 73,401,240 and divide it by 2.

In this case, 73,401,240 ÷ 2 = 36,700,620

If the quotient is a whole number, then 2 and 36,700,620 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 36,700,620 73,401,240

Now, we try dividing 73,401,240 by 3.

73,401,240 ÷ 3 = 24,467,080

If the quotient is a whole number, then 3 and 24,467,080 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 24,467,080 36,700,620 73,401,240

Let's try dividing by 4.

73,401,240 ÷ 4 = 18,350,310

If the quotient is a whole number, then 4 and 18,350,310 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 18,350,310 24,467,080 36,700,620 73,401,240

We keep dividing by the next largest number, in this case the number 5. If the quotient of 73,401,240 ÷ 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:
