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 1,127,897, 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 | 1,127,897 | |
| -1 | -1,127,897 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,127,897.
Example:
1 x 1,127,897 = 1,127,897
and
-1 x -1,127,897 = 1,127,897
Notice both answers equal 1,127,897
With that explanation out of the way, let's continue. Next, we take the number 1,127,897 and divide it by 2:
1,127,897 ÷ 2 = 563,948.5
If the quotient is a whole number, then 2 and 563,948.5 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 | 1,127,897 | |
| -1 | -1,127,897 |
Now, we try dividing 1,127,897 by 3:
1,127,897 ÷ 3 = 375,965.6667
If the quotient is a whole number, then 3 and 375,965.6667 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 | 1,127,897 | |
| -1 | -1,127,897 |
Let's try dividing by 4:
1,127,897 ÷ 4 = 281,974.25
If the quotient is a whole number, then 4 and 281,974.25 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 | 1,127,897 | |
| -1 | 1,127,897 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 29 | 89 | 437 | 551 | 667 | 1,691 | 2,047 | 2,581 | 12,673 | 38,893 | 49,039 | 59,363 | 1,127,897 |
| -1 | -19 | -23 | -29 | -89 | -437 | -551 | -667 | -1,691 | -2,047 | -2,581 | -12,673 | -38,893 | -49,039 | -59,363 | -1,127,897 |
