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 32,186,423, 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 | 32,186,423 | |
| -1 | -32,186,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,186,423.
Example:
1 x 32,186,423 = 32,186,423
and
-1 x -32,186,423 = 32,186,423
Notice both answers equal 32,186,423
With that explanation out of the way, let's continue. Next, we take the number 32,186,423 and divide it by 2:
32,186,423 ÷ 2 = 16,093,211.5
If the quotient is a whole number, then 2 and 16,093,211.5 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 | 32,186,423 | |
| -1 | -32,186,423 |
Now, we try dividing 32,186,423 by 3:
32,186,423 ÷ 3 = 10,728,807.6667
If the quotient is a whole number, then 3 and 10,728,807.6667 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 | 32,186,423 | |
| -1 | -32,186,423 |
Let's try dividing by 4:
32,186,423 ÷ 4 = 8,046,605.75
If the quotient is a whole number, then 4 and 8,046,605.75 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 | 32,186,423 | |
| -1 | 32,186,423 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 139 | 257 | 901 | 2,363 | 4,369 | 7,367 | 13,621 | 35,723 | 125,239 | 231,557 | 607,291 | 1,893,319 | 32,186,423 |
| -1 | -17 | -53 | -139 | -257 | -901 | -2,363 | -4,369 | -7,367 | -13,621 | -35,723 | -125,239 | -231,557 | -607,291 | -1,893,319 | -32,186,423 |
