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 715,225, 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 | 715,225 | |
| -1 | -715,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 715,225.
Example:
1 x 715,225 = 715,225
and
-1 x -715,225 = 715,225
Notice both answers equal 715,225
With that explanation out of the way, let's continue. Next, we take the number 715,225 and divide it by 2:
715,225 ÷ 2 = 357,612.5
If the quotient is a whole number, then 2 and 357,612.5 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 | 715,225 | |
| -1 | -715,225 |
Now, we try dividing 715,225 by 3:
715,225 ÷ 3 = 238,408.3333
If the quotient is a whole number, then 3 and 238,408.3333 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 | 715,225 | |
| -1 | -715,225 |
Let's try dividing by 4:
715,225 ÷ 4 = 178,806.25
If the quotient is a whole number, then 4 and 178,806.25 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 | 715,225 | |
| -1 | 715,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 61 | 67 | 175 | 305 | 335 | 427 | 469 | 1,525 | 1,675 | 2,135 | 2,345 | 4,087 | 10,675 | 11,725 | 20,435 | 28,609 | 102,175 | 143,045 | 715,225 |
| -1 | -5 | -7 | -25 | -35 | -61 | -67 | -175 | -305 | -335 | -427 | -469 | -1,525 | -1,675 | -2,135 | -2,345 | -4,087 | -10,675 | -11,725 | -20,435 | -28,609 | -102,175 | -143,045 | -715,225 |
