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 15,524,275, 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 | 15,524,275 | |
| -1 | -15,524,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,524,275.
Example:
1 x 15,524,275 = 15,524,275
and
-1 x -15,524,275 = 15,524,275
Notice both answers equal 15,524,275
With that explanation out of the way, let's continue. Next, we take the number 15,524,275 and divide it by 2:
15,524,275 ÷ 2 = 7,762,137.5
If the quotient is a whole number, then 2 and 7,762,137.5 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 | 15,524,275 | |
| -1 | -15,524,275 |
Now, we try dividing 15,524,275 by 3:
15,524,275 ÷ 3 = 5,174,758.3333
If the quotient is a whole number, then 3 and 5,174,758.3333 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 | 15,524,275 | |
| -1 | -15,524,275 |
Let's try dividing by 4:
15,524,275 ÷ 4 = 3,881,068.75
If the quotient is a whole number, then 4 and 3,881,068.75 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 | 15,524,275 | |
| -1 | 15,524,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 37 | 65 | 185 | 325 | 481 | 925 | 1,291 | 2,405 | 6,455 | 12,025 | 16,783 | 32,275 | 47,767 | 83,915 | 238,835 | 419,575 | 620,971 | 1,194,175 | 3,104,855 | 15,524,275 |
| -1 | -5 | -13 | -25 | -37 | -65 | -185 | -325 | -481 | -925 | -1,291 | -2,405 | -6,455 | -12,025 | -16,783 | -32,275 | -47,767 | -83,915 | -238,835 | -419,575 | -620,971 | -1,194,175 | -3,104,855 | -15,524,275 |
