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 15,601,525, 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 | 15,601,525 | |
| -1 | -15,601,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,601,525.
Example:
1 x 15,601,525 = 15,601,525
and
-1 x -15,601,525 = 15,601,525
Notice both answers equal 15,601,525
With that explanation out of the way, let's continue. Next, we take the number 15,601,525 and divide it by 2:
15,601,525 ÷ 2 = 7,800,762.5
If the quotient is a whole number, then 2 and 7,800,762.5 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 | 15,601,525 | |
| -1 | -15,601,525 |
Now, we try dividing 15,601,525 by 3:
15,601,525 ÷ 3 = 5,200,508.3333
If the quotient is a whole number, then 3 and 5,200,508.3333 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 | 15,601,525 | |
| -1 | -15,601,525 |
Let's try dividing by 4:
15,601,525 ÷ 4 = 3,900,381.25
If the quotient is a whole number, then 4 and 3,900,381.25 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 | 15,601,525 | |
| -1 | 15,601,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 41 | 155 | 205 | 491 | 775 | 1,025 | 1,271 | 2,455 | 6,355 | 12,275 | 15,221 | 20,131 | 31,775 | 76,105 | 100,655 | 380,525 | 503,275 | 624,061 | 3,120,305 | 15,601,525 |
| -1 | -5 | -25 | -31 | -41 | -155 | -205 | -491 | -775 | -1,025 | -1,271 | -2,455 | -6,355 | -12,275 | -15,221 | -20,131 | -31,775 | -76,105 | -100,655 | -380,525 | -503,275 | -624,061 | -3,120,305 | -15,601,525 |
