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 10,415,251, 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 | 10,415,251 | |
| -1 | -10,415,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,415,251.
Example:
1 x 10,415,251 = 10,415,251
and
-1 x -10,415,251 = 10,415,251
Notice both answers equal 10,415,251
With that explanation out of the way, let's continue. Next, we take the number 10,415,251 and divide it by 2:
10,415,251 ÷ 2 = 5,207,625.5
If the quotient is a whole number, then 2 and 5,207,625.5 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 | 10,415,251 | |
| -1 | -10,415,251 |
Now, we try dividing 10,415,251 by 3:
10,415,251 ÷ 3 = 3,471,750.3333
If the quotient is a whole number, then 3 and 3,471,750.3333 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 | 10,415,251 | |
| -1 | -10,415,251 |
Let's try dividing by 4:
10,415,251 ÷ 4 = 2,603,812.75
If the quotient is a whole number, then 4 and 2,603,812.75 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 | 10,415,251 | |
| -1 | 10,415,251 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 5,881 | 41,167 | 64,691 | 135,263 | 452,837 | 946,841 | 1,487,893 | 10,415,251 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -5,881 | -41,167 | -64,691 | -135,263 | -452,837 | -946,841 | -1,487,893 | -10,415,251 |
