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 99,522,893, 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 | 99,522,893 | |
| -1 | -99,522,893 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 99,522,893.
Example:
1 x 99,522,893 = 99,522,893
and
-1 x -99,522,893 = 99,522,893
Notice both answers equal 99,522,893
With that explanation out of the way, let's continue. Next, we take the number 99,522,893 and divide it by 2:
99,522,893 ÷ 2 = 49,761,446.5
If the quotient is a whole number, then 2 and 49,761,446.5 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 | 99,522,893 | |
| -1 | -99,522,893 |
Now, we try dividing 99,522,893 by 3:
99,522,893 ÷ 3 = 33,174,297.6667
If the quotient is a whole number, then 3 and 33,174,297.6667 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 | 99,522,893 | |
| -1 | -99,522,893 |
Let's try dividing by 4:
99,522,893 ÷ 4 = 24,880,723.25
If the quotient is a whole number, then 4 and 24,880,723.25 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 | 99,522,893 | |
| -1 | 99,522,893 |
If you did it right, you will end up with this table:
| 1 | 19 | 83 | 223 | 283 | 1,577 | 4,237 | 5,377 | 18,509 | 23,489 | 63,109 | 351,671 | 446,291 | 1,199,071 | 5,238,047 | 99,522,893 |
| -1 | -19 | -83 | -223 | -283 | -1,577 | -4,237 | -5,377 | -18,509 | -23,489 | -63,109 | -351,671 | -446,291 | -1,199,071 | -5,238,047 | -99,522,893 |
