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 1,558,271, 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 | 1,558,271 | |
| -1 | -1,558,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,558,271.
Example:
1 x 1,558,271 = 1,558,271
and
-1 x -1,558,271 = 1,558,271
Notice both answers equal 1,558,271
With that explanation out of the way, let's continue. Next, we take the number 1,558,271 and divide it by 2:
1,558,271 ÷ 2 = 779,135.5
If the quotient is a whole number, then 2 and 779,135.5 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 | 1,558,271 | |
| -1 | -1,558,271 |
Now, we try dividing 1,558,271 by 3:
1,558,271 ÷ 3 = 519,423.6667
If the quotient is a whole number, then 3 and 519,423.6667 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 | 1,558,271 | |
| -1 | -1,558,271 |
Let's try dividing by 4:
1,558,271 ÷ 4 = 389,567.75
If the quotient is a whole number, then 4 and 389,567.75 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 | 1,558,271 | |
| -1 | 1,558,271 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 641 | 2,431 | 7,051 | 8,333 | 10,897 | 91,663 | 119,867 | 141,661 | 1,558,271 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -641 | -2,431 | -7,051 | -8,333 | -10,897 | -91,663 | -119,867 | -141,661 | -1,558,271 |
