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 287,525, 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 | 287,525 | |
| -1 | -287,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 287,525.
Example:
1 x 287,525 = 287,525
and
-1 x -287,525 = 287,525
Notice both answers equal 287,525
With that explanation out of the way, let's continue. Next, we take the number 287,525 and divide it by 2:
287,525 ÷ 2 = 143,762.5
If the quotient is a whole number, then 2 and 143,762.5 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 | 287,525 | |
| -1 | -287,525 |
Now, we try dividing 287,525 by 3:
287,525 ÷ 3 = 95,841.6667
If the quotient is a whole number, then 3 and 95,841.6667 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 | 287,525 | |
| -1 | -287,525 |
Let's try dividing by 4:
287,525 ÷ 4 = 71,881.25
If the quotient is a whole number, then 4 and 71,881.25 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 | 287,525 | |
| -1 | 287,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 53 | 155 | 175 | 217 | 265 | 371 | 775 | 1,085 | 1,325 | 1,643 | 1,855 | 5,425 | 8,215 | 9,275 | 11,501 | 41,075 | 57,505 | 287,525 |
| -1 | -5 | -7 | -25 | -31 | -35 | -53 | -155 | -175 | -217 | -265 | -371 | -775 | -1,085 | -1,325 | -1,643 | -1,855 | -5,425 | -8,215 | -9,275 | -11,501 | -41,075 | -57,505 | -287,525 |
