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 499,525, 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 | 499,525 | |
| -1 | -499,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 499,525.
Example:
1 x 499,525 = 499,525
and
-1 x -499,525 = 499,525
Notice both answers equal 499,525
With that explanation out of the way, let's continue. Next, we take the number 499,525 and divide it by 2:
499,525 ÷ 2 = 249,762.5
If the quotient is a whole number, then 2 and 249,762.5 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 | 499,525 | |
| -1 | -499,525 |
Now, we try dividing 499,525 by 3:
499,525 ÷ 3 = 166,508.3333
If the quotient is a whole number, then 3 and 166,508.3333 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 | 499,525 | |
| -1 | -499,525 |
Let's try dividing by 4:
499,525 ÷ 4 = 124,881.25
If the quotient is a whole number, then 4 and 124,881.25 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 | 499,525 | |
| -1 | 499,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 29 | 53 | 65 | 145 | 265 | 325 | 377 | 689 | 725 | 1,325 | 1,537 | 1,885 | 3,445 | 7,685 | 9,425 | 17,225 | 19,981 | 38,425 | 99,905 | 499,525 |
| -1 | -5 | -13 | -25 | -29 | -53 | -65 | -145 | -265 | -325 | -377 | -689 | -725 | -1,325 | -1,537 | -1,885 | -3,445 | -7,685 | -9,425 | -17,225 | -19,981 | -38,425 | -99,905 | -499,525 |
