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 245,575, 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 | 245,575 | |
| -1 | -245,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,575.
Example:
1 x 245,575 = 245,575
and
-1 x -245,575 = 245,575
Notice both answers equal 245,575
With that explanation out of the way, let's continue. Next, we take the number 245,575 and divide it by 2:
245,575 ÷ 2 = 122,787.5
If the quotient is a whole number, then 2 and 122,787.5 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 | 245,575 | |
| -1 | -245,575 |
Now, we try dividing 245,575 by 3:
245,575 ÷ 3 = 81,858.3333
If the quotient is a whole number, then 3 and 81,858.3333 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 | 245,575 | |
| -1 | -245,575 |
Let's try dividing by 4:
245,575 ÷ 4 = 61,393.75
If the quotient is a whole number, then 4 and 61,393.75 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 | 245,575 | |
| -1 | 245,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 25 | 47 | 55 | 95 | 209 | 235 | 275 | 475 | 517 | 893 | 1,045 | 1,175 | 2,585 | 4,465 | 5,225 | 9,823 | 12,925 | 22,325 | 49,115 | 245,575 |
| -1 | -5 | -11 | -19 | -25 | -47 | -55 | -95 | -209 | -235 | -275 | -475 | -517 | -893 | -1,045 | -1,175 | -2,585 | -4,465 | -5,225 | -9,823 | -12,925 | -22,325 | -49,115 | -245,575 |
