How do I find the factors or divisors of the number 240,200,420?

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 240,200,420, 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.

1 240,200,420

Next, we take the number 240,200,420 and divide it by 2.

In this case, 240,200,420 ÷ 2 = 120,100,210

If the quotient is a whole number, then 2 and 120,100,210 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 120,100,210 240,200,420

Now, we try dividing 240,200,420 by 3.

240,200,420 ÷ 3 = 80,066,806.6667

If the quotient is a whole number, then 3 and 80,066,806.6667 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 2 120,100,210 240,200,420

Let's try dividing by 4.

240,200,420 ÷ 4 = 60,050,105

If the quotient is a whole number, then 4 and 60,050,105 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 4 60,050,105 120,100,210 240,200,420

We keep dividing by the next largest number, in this case the number 5. If the quotient of 240,200,420 ÷ 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:

1245102012,010,02124,020,04248,040,08460,050,105120,100,210240,200,420

All of the numbers in the table above can be evenly divided into the number 240,200,420.
