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 10,926,545, 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 | 10,926,545 | |
| -1 | -10,926,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,926,545.
Example:
1 x 10,926,545 = 10,926,545
and
-1 x -10,926,545 = 10,926,545
Notice both answers equal 10,926,545
With that explanation out of the way, let's continue. Next, we take the number 10,926,545 and divide it by 2:
10,926,545 ÷ 2 = 5,463,272.5
If the quotient is a whole number, then 2 and 5,463,272.5 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 | 10,926,545 | |
| -1 | -10,926,545 |
Now, we try dividing 10,926,545 by 3:
10,926,545 ÷ 3 = 3,642,181.6667
If the quotient is a whole number, then 3 and 3,642,181.6667 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 | 10,926,545 | |
| -1 | -10,926,545 |
Let's try dividing by 4:
10,926,545 ÷ 4 = 2,731,636.25
If the quotient is a whole number, then 4 and 2,731,636.25 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 | 10,926,545 | |
| -1 | 10,926,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 4,397 | 21,985 | 30,779 | 153,895 | 312,187 | 1,560,935 | 2,185,309 | 10,926,545 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -4,397 | -21,985 | -30,779 | -153,895 | -312,187 | -1,560,935 | -2,185,309 | -10,926,545 |
