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 13,250,503, 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 | 13,250,503 | |
| -1 | -13,250,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,250,503.
Example:
1 x 13,250,503 = 13,250,503
and
-1 x -13,250,503 = 13,250,503
Notice both answers equal 13,250,503
With that explanation out of the way, let's continue. Next, we take the number 13,250,503 and divide it by 2:
13,250,503 ÷ 2 = 6,625,251.5
If the quotient is a whole number, then 2 and 6,625,251.5 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 | 13,250,503 | |
| -1 | -13,250,503 |
Now, we try dividing 13,250,503 by 3:
13,250,503 ÷ 3 = 4,416,834.3333
If the quotient is a whole number, then 3 and 4,416,834.3333 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 | 13,250,503 | |
| -1 | -13,250,503 |
Let's try dividing by 4:
13,250,503 ÷ 4 = 3,312,625.75
If the quotient is a whole number, then 4 and 3,312,625.75 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 | 13,250,503 | |
| -1 | 13,250,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 137 | 287 | 337 | 959 | 2,359 | 5,617 | 13,817 | 39,319 | 46,169 | 96,719 | 323,183 | 1,892,929 | 13,250,503 |
| -1 | -7 | -41 | -137 | -287 | -337 | -959 | -2,359 | -5,617 | -13,817 | -39,319 | -46,169 | -96,719 | -323,183 | -1,892,929 | -13,250,503 |
