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 10,640,273, 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 | 10,640,273 | |
| -1 | -10,640,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,640,273.
Example:
1 x 10,640,273 = 10,640,273
and
-1 x -10,640,273 = 10,640,273
Notice both answers equal 10,640,273
With that explanation out of the way, let's continue. Next, we take the number 10,640,273 and divide it by 2:
10,640,273 ÷ 2 = 5,320,136.5
If the quotient is a whole number, then 2 and 5,320,136.5 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 | 10,640,273 | |
| -1 | -10,640,273 |
Now, we try dividing 10,640,273 by 3:
10,640,273 ÷ 3 = 3,546,757.6667
If the quotient is a whole number, then 3 and 3,546,757.6667 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 | 10,640,273 | |
| -1 | -10,640,273 |
Let's try dividing by 4:
10,640,273 ÷ 4 = 2,660,068.25
If the quotient is a whole number, then 4 and 2,660,068.25 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 | 10,640,273 | |
| -1 | 10,640,273 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 79 | 271 | 497 | 553 | 1,897 | 5,609 | 19,241 | 21,409 | 39,263 | 134,687 | 149,863 | 1,520,039 | 10,640,273 |
| -1 | -7 | -71 | -79 | -271 | -497 | -553 | -1,897 | -5,609 | -19,241 | -21,409 | -39,263 | -134,687 | -149,863 | -1,520,039 | -10,640,273 |
