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 84,044,441, 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 | 84,044,441 | |
| -1 | -84,044,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,044,441.
Example:
1 x 84,044,441 = 84,044,441
and
-1 x -84,044,441 = 84,044,441
Notice both answers equal 84,044,441
With that explanation out of the way, let's continue. Next, we take the number 84,044,441 and divide it by 2:
84,044,441 ÷ 2 = 42,022,220.5
If the quotient is a whole number, then 2 and 42,022,220.5 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 | 84,044,441 | |
| -1 | -84,044,441 |
Now, we try dividing 84,044,441 by 3:
84,044,441 ÷ 3 = 28,014,813.6667
If the quotient is a whole number, then 3 and 28,014,813.6667 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 | 84,044,441 | |
| -1 | -84,044,441 |
Let's try dividing by 4:
84,044,441 ÷ 4 = 21,011,110.25
If the quotient is a whole number, then 4 and 21,011,110.25 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 | 84,044,441 | |
| -1 | 84,044,441 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 347 | 403 | 601 | 4,511 | 7,813 | 10,757 | 18,631 | 139,841 | 208,547 | 242,203 | 2,711,111 | 6,464,957 | 84,044,441 |
| -1 | -13 | -31 | -347 | -403 | -601 | -4,511 | -7,813 | -10,757 | -18,631 | -139,841 | -208,547 | -242,203 | -2,711,111 | -6,464,957 | -84,044,441 |
