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 12,757,283, 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 | 12,757,283 | |
| -1 | -12,757,283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,757,283.
Example:
1 x 12,757,283 = 12,757,283
and
-1 x -12,757,283 = 12,757,283
Notice both answers equal 12,757,283
With that explanation out of the way, let's continue. Next, we take the number 12,757,283 and divide it by 2:
12,757,283 ÷ 2 = 6,378,641.5
If the quotient is a whole number, then 2 and 6,378,641.5 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 | 12,757,283 | |
| -1 | -12,757,283 |
Now, we try dividing 12,757,283 by 3:
12,757,283 ÷ 3 = 4,252,427.6667
If the quotient is a whole number, then 3 and 4,252,427.6667 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 | 12,757,283 | |
| -1 | -12,757,283 |
Let's try dividing by 4:
12,757,283 ÷ 4 = 3,189,320.75
If the quotient is a whole number, then 4 and 3,189,320.75 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 | 12,757,283 | |
| -1 | 12,757,283 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 43 | 77 | 301 | 473 | 3,311 | 3,853 | 26,971 | 42,383 | 165,679 | 296,681 | 1,159,753 | 1,822,469 | 12,757,283 |
| -1 | -7 | -11 | -43 | -77 | -301 | -473 | -3,311 | -3,853 | -26,971 | -42,383 | -165,679 | -296,681 | -1,159,753 | -1,822,469 | -12,757,283 |
