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 739,025, 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 | 739,025 | |
| -1 | -739,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 739,025.
Example:
1 x 739,025 = 739,025
and
-1 x -739,025 = 739,025
Notice both answers equal 739,025
With that explanation out of the way, let's continue. Next, we take the number 739,025 and divide it by 2:
739,025 ÷ 2 = 369,512.5
If the quotient is a whole number, then 2 and 369,512.5 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 | 739,025 | |
| -1 | -739,025 |
Now, we try dividing 739,025 by 3:
739,025 ÷ 3 = 246,341.6667
If the quotient is a whole number, then 3 and 246,341.6667 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 | 739,025 | |
| -1 | -739,025 |
Let's try dividing by 4:
739,025 ÷ 4 = 184,756.25
If the quotient is a whole number, then 4 and 184,756.25 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 | 739,025 | |
| -1 | 739,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 41 | 103 | 175 | 205 | 287 | 515 | 721 | 1,025 | 1,435 | 2,575 | 3,605 | 4,223 | 7,175 | 18,025 | 21,115 | 29,561 | 105,575 | 147,805 | 739,025 |
| -1 | -5 | -7 | -25 | -35 | -41 | -103 | -175 | -205 | -287 | -515 | -721 | -1,025 | -1,435 | -2,575 | -3,605 | -4,223 | -7,175 | -18,025 | -21,115 | -29,561 | -105,575 | -147,805 | -739,025 |
