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 10,772,447, 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 | 10,772,447 | |
| -1 | -10,772,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,772,447.
Example:
1 x 10,772,447 = 10,772,447
and
-1 x -10,772,447 = 10,772,447
Notice both answers equal 10,772,447
With that explanation out of the way, let's continue. Next, we take the number 10,772,447 and divide it by 2:
10,772,447 ÷ 2 = 5,386,223.5
If the quotient is a whole number, then 2 and 5,386,223.5 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 | 10,772,447 | |
| -1 | -10,772,447 |
Now, we try dividing 10,772,447 by 3:
10,772,447 ÷ 3 = 3,590,815.6667
If the quotient is a whole number, then 3 and 3,590,815.6667 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 | 10,772,447 | |
| -1 | -10,772,447 |
Let's try dividing by 4:
10,772,447 ÷ 4 = 2,693,111.75
If the quotient is a whole number, then 4 and 2,693,111.75 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 | 10,772,447 | |
| -1 | 10,772,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 137 | 239 | 329 | 959 | 1,673 | 6,439 | 11,233 | 32,743 | 45,073 | 78,631 | 229,201 | 1,538,921 | 10,772,447 |
| -1 | -7 | -47 | -137 | -239 | -329 | -959 | -1,673 | -6,439 | -11,233 | -32,743 | -45,073 | -78,631 | -229,201 | -1,538,921 | -10,772,447 |
