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 1,237,093, 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 | 1,237,093 | |
| -1 | -1,237,093 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,237,093.
Example:
1 x 1,237,093 = 1,237,093
and
-1 x -1,237,093 = 1,237,093
Notice both answers equal 1,237,093
With that explanation out of the way, let's continue. Next, we take the number 1,237,093 and divide it by 2:
1,237,093 ÷ 2 = 618,546.5
If the quotient is a whole number, then 2 and 618,546.5 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 | 1,237,093 | |
| -1 | -1,237,093 |
Now, we try dividing 1,237,093 by 3:
1,237,093 ÷ 3 = 412,364.3333
If the quotient is a whole number, then 3 and 412,364.3333 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 | 1,237,093 | |
| -1 | -1,237,093 |
Let's try dividing by 4:
1,237,093 ÷ 4 = 309,273.25
If the quotient is a whole number, then 4 and 309,273.25 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 | 1,237,093 | |
| -1 | 1,237,093 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 41 | 143 | 211 | 451 | 533 | 2,321 | 2,743 | 5,863 | 8,651 | 30,173 | 95,161 | 112,463 | 1,237,093 |
| -1 | -11 | -13 | -41 | -143 | -211 | -451 | -533 | -2,321 | -2,743 | -5,863 | -8,651 | -30,173 | -95,161 | -112,463 | -1,237,093 |
