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 15,555,463, 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 | 15,555,463 | |
| -1 | -15,555,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,555,463.
Example:
1 x 15,555,463 = 15,555,463
and
-1 x -15,555,463 = 15,555,463
Notice both answers equal 15,555,463
With that explanation out of the way, let's continue. Next, we take the number 15,555,463 and divide it by 2:
15,555,463 ÷ 2 = 7,777,731.5
If the quotient is a whole number, then 2 and 7,777,731.5 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 | 15,555,463 | |
| -1 | -15,555,463 |
Now, we try dividing 15,555,463 by 3:
15,555,463 ÷ 3 = 5,185,154.3333
If the quotient is a whole number, then 3 and 5,185,154.3333 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 | 15,555,463 | |
| -1 | -15,555,463 |
Let's try dividing by 4:
15,555,463 ÷ 4 = 3,888,865.75
If the quotient is a whole number, then 4 and 3,888,865.75 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 | 15,555,463 | |
| -1 | 15,555,463 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 269 | 751 | 1,883 | 2,959 | 5,257 | 8,261 | 20,713 | 57,827 | 202,019 | 1,414,133 | 2,222,209 | 15,555,463 |
| -1 | -7 | -11 | -77 | -269 | -751 | -1,883 | -2,959 | -5,257 | -8,261 | -20,713 | -57,827 | -202,019 | -1,414,133 | -2,222,209 | -15,555,463 |
