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 1,558,025, 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 | 1,558,025 | |
| -1 | -1,558,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,558,025.
Example:
1 x 1,558,025 = 1,558,025
and
-1 x -1,558,025 = 1,558,025
Notice both answers equal 1,558,025
With that explanation out of the way, let's continue. Next, we take the number 1,558,025 and divide it by 2:
1,558,025 ÷ 2 = 779,012.5
If the quotient is a whole number, then 2 and 779,012.5 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 | 1,558,025 | |
| -1 | -1,558,025 |
Now, we try dividing 1,558,025 by 3:
1,558,025 ÷ 3 = 519,341.6667
If the quotient is a whole number, then 3 and 519,341.6667 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 | 1,558,025 | |
| -1 | -1,558,025 |
Let's try dividing by 4:
1,558,025 ÷ 4 = 389,506.25
If the quotient is a whole number, then 4 and 389,506.25 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 | 1,558,025 | |
| -1 | 1,558,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 307 | 725 | 1,015 | 1,535 | 2,149 | 5,075 | 7,675 | 8,903 | 10,745 | 44,515 | 53,725 | 62,321 | 222,575 | 311,605 | 1,558,025 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -307 | -725 | -1,015 | -1,535 | -2,149 | -5,075 | -7,675 | -8,903 | -10,745 | -44,515 | -53,725 | -62,321 | -222,575 | -311,605 | -1,558,025 |
