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 84,443,429, 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 | 84,443,429 | |
| -1 | -84,443,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,443,429.
Example:
1 x 84,443,429 = 84,443,429
and
-1 x -84,443,429 = 84,443,429
Notice both answers equal 84,443,429
With that explanation out of the way, let's continue. Next, we take the number 84,443,429 and divide it by 2:
84,443,429 ÷ 2 = 42,221,714.5
If the quotient is a whole number, then 2 and 42,221,714.5 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 | 84,443,429 | |
| -1 | -84,443,429 |
Now, we try dividing 84,443,429 by 3:
84,443,429 ÷ 3 = 28,147,809.6667
If the quotient is a whole number, then 3 and 28,147,809.6667 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 | 84,443,429 | |
| -1 | -84,443,429 |
Let's try dividing by 4:
84,443,429 ÷ 4 = 21,110,857.25
If the quotient is a whole number, then 4 and 21,110,857.25 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 | 84,443,429 | |
| -1 | 84,443,429 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 179 | 1,253 | 3,401 | 3,547 | 23,807 | 24,829 | 67,393 | 471,751 | 634,913 | 4,444,391 | 12,063,347 | 84,443,429 |
| -1 | -7 | -19 | -133 | -179 | -1,253 | -3,401 | -3,547 | -23,807 | -24,829 | -67,393 | -471,751 | -634,913 | -4,444,391 | -12,063,347 | -84,443,429 |
