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 918,775, 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 | 918,775 | |
| -1 | -918,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 918,775.
Example:
1 x 918,775 = 918,775
and
-1 x -918,775 = 918,775
Notice both answers equal 918,775
With that explanation out of the way, let's continue. Next, we take the number 918,775 and divide it by 2:
918,775 ÷ 2 = 459,387.5
If the quotient is a whole number, then 2 and 459,387.5 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 | 918,775 | |
| -1 | -918,775 |
Now, we try dividing 918,775 by 3:
918,775 ÷ 3 = 306,258.3333
If the quotient is a whole number, then 3 and 306,258.3333 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 | 918,775 | |
| -1 | -918,775 |
Let's try dividing by 4:
918,775 ÷ 4 = 229,693.75
If the quotient is a whole number, then 4 and 229,693.75 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 | 918,775 | |
| -1 | 918,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 257 | 275 | 325 | 715 | 1,285 | 2,827 | 3,341 | 3,575 | 6,425 | 14,135 | 16,705 | 36,751 | 70,675 | 83,525 | 183,755 | 918,775 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -257 | -275 | -325 | -715 | -1,285 | -2,827 | -3,341 | -3,575 | -6,425 | -14,135 | -16,705 | -36,751 | -70,675 | -83,525 | -183,755 | -918,775 |
