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 1,337,791, 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 | 1,337,791 | |
| -1 | -1,337,791 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,337,791.
Example:
1 x 1,337,791 = 1,337,791
and
-1 x -1,337,791 = 1,337,791
Notice both answers equal 1,337,791
With that explanation out of the way, let's continue. Next, we take the number 1,337,791 and divide it by 2:
1,337,791 ÷ 2 = 668,895.5
If the quotient is a whole number, then 2 and 668,895.5 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 | 1,337,791 | |
| -1 | -1,337,791 |
Now, we try dividing 1,337,791 by 3:
1,337,791 ÷ 3 = 445,930.3333
If the quotient is a whole number, then 3 and 445,930.3333 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 | 1,337,791 | |
| -1 | -1,337,791 |
Let's try dividing by 4:
1,337,791 ÷ 4 = 334,447.75
If the quotient is a whole number, then 4 and 334,447.75 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 | 1,337,791 | |
| -1 | 1,337,791 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 61 | 91 | 241 | 427 | 793 | 1,687 | 3,133 | 5,551 | 14,701 | 21,931 | 102,907 | 191,113 | 1,337,791 |
| -1 | -7 | -13 | -61 | -91 | -241 | -427 | -793 | -1,687 | -3,133 | -5,551 | -14,701 | -21,931 | -102,907 | -191,113 | -1,337,791 |
