How do I find the factors or divisors of the number 42,120,240?

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 42,120,240, 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 42,120,240

Next, we take the number 42,120,240 and divide it by 2.

In this case, 42,120,240 ÷ 2 = 21,060,120

If the quotient is a whole number, then 2 and 21,060,120 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 21,060,120 42,120,240

Now, we try dividing 42,120,240 by 3.

42,120,240 ÷ 3 = 14,040,080

If the quotient is a whole number, then 3 and 14,040,080 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 14,040,080 21,060,120 42,120,240

Let's try dividing by 4.

42,120,240 ÷ 4 = 10,530,060

If the quotient is a whole number, then 4 and 10,530,060 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 10,530,060 14,040,080 21,060,120 42,120,240

We keep dividing by the next largest number, in this case the number 5. If the quotient of 42,120,240 ÷ 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:
