How do I find the factors or divisors of the number 742,221,372?

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 742,221,372, 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.

1 742,221,372

Next, we take the number 742,221,372 and divide it by 2.

In this case, 742,221,372 ÷ 2 = 371,110,686

If the quotient is a whole number, then 2 and 371,110,686 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 371,110,686 742,221,372

Now, we try dividing 742,221,372 by 3.

742,221,372 ÷ 3 = 247,407,124

If the quotient is a whole number, then 3 and 247,407,124 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 3 247,407,124 371,110,686 742,221,372

Let's try dividing by 4.

742,221,372 ÷ 4 = 185,555,343

If the quotient is a whole number, then 4 and 185,555,343 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 4 185,555,343 247,407,124 371,110,686 742,221,372

We keep dividing by the next largest number, in this case the number 5. If the quotient of 742,221,372 ÷ 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:

12346121312623935247861,572472,151944,3021,416,4531,888,6042,832,9065,665,81261,851,781123,703,562185,555,343247,407,124371,110,686742,221,372

All of the numbers in the table above can be evenly divided into the number 742,221,372.
