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 100,012,297, 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 | 100,012,297 | |
| -1 | -100,012,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,012,297.
Example:
1 x 100,012,297 = 100,012,297
and
-1 x -100,012,297 = 100,012,297
Notice both answers equal 100,012,297
With that explanation out of the way, let's continue. Next, we take the number 100,012,297 and divide it by 2:
100,012,297 ÷ 2 = 50,006,148.5
If the quotient is a whole number, then 2 and 50,006,148.5 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 | 100,012,297 | |
| -1 | -100,012,297 |
Now, we try dividing 100,012,297 by 3:
100,012,297 ÷ 3 = 33,337,432.3333
If the quotient is a whole number, then 3 and 33,337,432.3333 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 | 100,012,297 | |
| -1 | -100,012,297 |
Let's try dividing by 4:
100,012,297 ÷ 4 = 25,003,074.25
If the quotient is a whole number, then 4 and 25,003,074.25 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 | 100,012,297 | |
| -1 | 100,012,297 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 157 | 1,099 | 1,727 | 8,273 | 12,089 | 57,911 | 91,003 | 637,021 | 1,298,861 | 9,092,027 | 14,287,471 | 100,012,297 |
| -1 | -7 | -11 | -77 | -157 | -1,099 | -1,727 | -8,273 | -12,089 | -57,911 | -91,003 | -637,021 | -1,298,861 | -9,092,027 | -14,287,471 | -100,012,297 |
