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 15,504,295, 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 | 15,504,295 | |
| -1 | -15,504,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,504,295.
Example:
1 x 15,504,295 = 15,504,295
and
-1 x -15,504,295 = 15,504,295
Notice both answers equal 15,504,295
With that explanation out of the way, let's continue. Next, we take the number 15,504,295 and divide it by 2:
15,504,295 ÷ 2 = 7,752,147.5
If the quotient is a whole number, then 2 and 7,752,147.5 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 | 15,504,295 | |
| -1 | -15,504,295 |
Now, we try dividing 15,504,295 by 3:
15,504,295 ÷ 3 = 5,168,098.3333
If the quotient is a whole number, then 3 and 5,168,098.3333 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 | 15,504,295 | |
| -1 | -15,504,295 |
Let's try dividing by 4:
15,504,295 ÷ 4 = 3,876,073.75
If the quotient is a whole number, then 4 and 3,876,073.75 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 | 15,504,295 | |
| -1 | 15,504,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 43 | 185 | 215 | 1,591 | 1,949 | 7,955 | 9,745 | 72,113 | 83,807 | 360,565 | 419,035 | 3,100,859 | 15,504,295 |
| -1 | -5 | -37 | -43 | -185 | -215 | -1,591 | -1,949 | -7,955 | -9,745 | -72,113 | -83,807 | -360,565 | -419,035 | -3,100,859 | -15,504,295 |
