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 10,972,291, 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 | 10,972,291 | |
| -1 | -10,972,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,972,291.
Example:
1 x 10,972,291 = 10,972,291
and
-1 x -10,972,291 = 10,972,291
Notice both answers equal 10,972,291
With that explanation out of the way, let's continue. Next, we take the number 10,972,291 and divide it by 2:
10,972,291 ÷ 2 = 5,486,145.5
If the quotient is a whole number, then 2 and 5,486,145.5 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 | 10,972,291 | |
| -1 | -10,972,291 |
Now, we try dividing 10,972,291 by 3:
10,972,291 ÷ 3 = 3,657,430.3333
If the quotient is a whole number, then 3 and 3,657,430.3333 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 | 10,972,291 | |
| -1 | -10,972,291 |
Let's try dividing by 4:
10,972,291 ÷ 4 = 2,743,072.75
If the quotient is a whole number, then 4 and 2,743,072.75 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 | 10,972,291 | |
| -1 | 10,972,291 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 47 | 209 | 517 | 893 | 1,117 | 9,823 | 12,287 | 21,223 | 52,499 | 233,453 | 577,489 | 997,481 | 10,972,291 |
| -1 | -11 | -19 | -47 | -209 | -517 | -893 | -1,117 | -9,823 | -12,287 | -21,223 | -52,499 | -233,453 | -577,489 | -997,481 | -10,972,291 |
