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 99,146,045, 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 | 99,146,045 | |
| -1 | -99,146,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 99,146,045.
Example:
1 x 99,146,045 = 99,146,045
and
-1 x -99,146,045 = 99,146,045
Notice both answers equal 99,146,045
With that explanation out of the way, let's continue. Next, we take the number 99,146,045 and divide it by 2:
99,146,045 ÷ 2 = 49,573,022.5
If the quotient is a whole number, then 2 and 49,573,022.5 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 | 99,146,045 | |
| -1 | -99,146,045 |
Now, we try dividing 99,146,045 by 3:
99,146,045 ÷ 3 = 33,048,681.6667
If the quotient is a whole number, then 3 and 33,048,681.6667 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 | 99,146,045 | |
| -1 | -99,146,045 |
Let's try dividing by 4:
99,146,045 ÷ 4 = 24,786,511.25
If the quotient is a whole number, then 4 and 24,786,511.25 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 | 99,146,045 | |
| -1 | 99,146,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 73 | 305 | 365 | 3,721 | 4,453 | 5,329 | 18,605 | 22,265 | 26,645 | 271,633 | 325,069 | 1,358,165 | 1,625,345 | 19,829,209 | 99,146,045 |
| -1 | -5 | -61 | -73 | -305 | -365 | -3,721 | -4,453 | -5,329 | -18,605 | -22,265 | -26,645 | -271,633 | -325,069 | -1,358,165 | -1,625,345 | -19,829,209 | -99,146,045 |
