How do I find the factors or divisors of the number 402,201,018?

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 402,201,018, 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.

1 402,201,018

Next, we take the number 402,201,018 and divide it by 2.

In this case, 402,201,018 ÷ 2 = 201,100,509

If the quotient is a whole number, then 2 and 201,100,509 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 201,100,509 402,201,018

Now, we try dividing 402,201,018 by 3.

402,201,018 ÷ 3 = 134,067,006

If the quotient is a whole number, then 3 and 134,067,006 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 3 134,067,006 201,100,509 402,201,018

Let's try dividing by 4.

402,201,018 ÷ 4 = 100,550,254.5

If the quotient is a whole number, then 4 and 100,550,254.5 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 3 134,067,006 201,100,509 402,201,018

We keep dividing by the next largest number, in this case the number 5. If the quotient of 402,201,018 ÷ 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:

123691827547,448,16714,896,33422,344,50144,689,00267,033,503134,067,006201,100,509402,201,018

All of the numbers in the table above can be evenly divided into the number 402,201,018.

Finally, for your reference, here are all of the divisor combinations of the number 402,201,018:

1 x 4022010182 x 2011005093 x 1340670066 x 670335039 x 4468900218 x 2234450127 x 1489633454 x 7448167
