How do I find the factors or divisors of the number 45,742,140?

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 45,742,140, 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 45,742,140

Next, we take the number 45,742,140 and divide it by 2.

In this case, 45,742,140 ÷ 2 = 22,871,070

If the quotient is a whole number, then 2 and 22,871,070 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 22,871,070 45,742,140

Now, we try dividing 45,742,140 by 3.

45,742,140 ÷ 3 = 15,247,380

If the quotient is a whole number, then 3 and 15,247,380 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 15,247,380 22,871,070 45,742,140

Let's try dividing by 4.

45,742,140 ÷ 4 = 11,435,535

If the quotient is a whole number, then 4 and 11,435,535 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 11,435,535 15,247,380 22,871,070 45,742,140

We keep dividing by the next largest number, in this case the number 5. If the quotient of 45,742,140 ÷ 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:
