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 10,451,413, 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 | 10,451,413 | |
| -1 | -10,451,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,451,413.
Example:
1 x 10,451,413 = 10,451,413
and
-1 x -10,451,413 = 10,451,413
Notice both answers equal 10,451,413
With that explanation out of the way, let's continue. Next, we take the number 10,451,413 and divide it by 2:
10,451,413 ÷ 2 = 5,225,706.5
If the quotient is a whole number, then 2 and 5,225,706.5 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 | 10,451,413 | |
| -1 | -10,451,413 |
Now, we try dividing 10,451,413 by 3:
10,451,413 ÷ 3 = 3,483,804.3333
If the quotient is a whole number, then 3 and 3,483,804.3333 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 | 10,451,413 | |
| -1 | -10,451,413 |
Let's try dividing by 4:
10,451,413 ÷ 4 = 2,612,853.25
If the quotient is a whole number, then 4 and 2,612,853.25 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 | 10,451,413 | |
| -1 | 10,451,413 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 71 | 119 | 497 | 1,207 | 1,237 | 8,449 | 8,659 | 21,029 | 87,827 | 147,203 | 614,789 | 1,493,059 | 10,451,413 |
| -1 | -7 | -17 | -71 | -119 | -497 | -1,207 | -1,237 | -8,449 | -8,659 | -21,029 | -87,827 | -147,203 | -614,789 | -1,493,059 | -10,451,413 |
