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 915,607, 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 | 915,607 | |
| -1 | -915,607 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 915,607.
Example:
1 x 915,607 = 915,607
and
-1 x -915,607 = 915,607
Notice both answers equal 915,607
With that explanation out of the way, let's continue. Next, we take the number 915,607 and divide it by 2:
915,607 ÷ 2 = 457,803.5
If the quotient is a whole number, then 2 and 457,803.5 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 | 915,607 | |
| -1 | -915,607 |
Now, we try dividing 915,607 by 3:
915,607 ÷ 3 = 305,202.3333
If the quotient is a whole number, then 3 and 305,202.3333 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 | 915,607 | |
| -1 | -915,607 |
Let's try dividing by 4:
915,607 ÷ 4 = 228,901.75
If the quotient is a whole number, then 4 and 228,901.75 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 | 915,607 | |
| -1 | 915,607 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 47 | 77 | 121 | 161 | 253 | 329 | 517 | 847 | 1,081 | 1,771 | 2,783 | 3,619 | 5,687 | 7,567 | 11,891 | 19,481 | 39,809 | 83,237 | 130,801 | 915,607 |
| -1 | -7 | -11 | -23 | -47 | -77 | -121 | -161 | -253 | -329 | -517 | -847 | -1,081 | -1,771 | -2,783 | -3,619 | -5,687 | -7,567 | -11,891 | -19,481 | -39,809 | -83,237 | -130,801 | -915,607 |
