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 986,575, 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 | 986,575 | |
| -1 | -986,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 986,575.
Example:
1 x 986,575 = 986,575
and
-1 x -986,575 = 986,575
Notice both answers equal 986,575
With that explanation out of the way, let's continue. Next, we take the number 986,575 and divide it by 2:
986,575 ÷ 2 = 493,287.5
If the quotient is a whole number, then 2 and 493,287.5 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 | 986,575 | |
| -1 | -986,575 |
Now, we try dividing 986,575 by 3:
986,575 ÷ 3 = 328,858.3333
If the quotient is a whole number, then 3 and 328,858.3333 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 | 986,575 | |
| -1 | -986,575 |
Let's try dividing by 4:
986,575 ÷ 4 = 246,643.75
If the quotient is a whole number, then 4 and 246,643.75 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 | 986,575 | |
| -1 | 986,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 31 | 67 | 95 | 155 | 335 | 475 | 589 | 775 | 1,273 | 1,675 | 2,077 | 2,945 | 6,365 | 10,385 | 14,725 | 31,825 | 39,463 | 51,925 | 197,315 | 986,575 |
| -1 | -5 | -19 | -25 | -31 | -67 | -95 | -155 | -335 | -475 | -589 | -775 | -1,273 | -1,675 | -2,077 | -2,945 | -6,365 | -10,385 | -14,725 | -31,825 | -39,463 | -51,925 | -197,315 | -986,575 |
