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 divisors of larger numbers. To find the factor combinations of the number 32,202,547, it is easier to work with a table - it's called factoring from the outside in.
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. Then, below that, write the numbers as a negative as well.
| 1 | 32,202,547 | |
| -1 | -32,202,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,202,547.
Example:
1 x 32,202,547 = 32,202,547
and
-1 x -32,202,547 = 32,202,547
Notice both answers equal 32,202,547
With that explanation out of the way, let's continue. Next, we take the number 32,202,547 and divide it by 2:
32,202,547 ÷ 2 = 16,101,273.5
If the quotient is a whole number, then 2 and 16,101,273.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,202,547 | |
| -1 | -32,202,547 |
Now, we try dividing 32,202,547 by 3:
32,202,547 ÷ 3 = 10,734,182.3333
If the quotient is a whole number, then 3 and 10,734,182.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,202,547 | |
| -1 | -32,202,547 |
Let's try dividing by 4:
32,202,547 ÷ 4 = 8,050,636.75
If the quotient is a whole number, then 4 and 8,050,636.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,202,547 | |
| -1 | 32,202,547 |
If you did it right, you will end up with this table:
| 1 | 13 | 71 | 139 | 251 | 923 | 1,807 | 3,263 | 9,869 | 17,821 | 34,889 | 128,297 | 231,673 | 453,557 | 2,477,119 | 32,202,547 |
| -1 | -13 | -71 | -139 | -251 | -923 | -1,807 | -3,263 | -9,869 | -17,821 | -34,889 | -128,297 | -231,673 | -453,557 | -2,477,119 | -32,202,547 |
