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 1,552,187, 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 | 1,552,187 | |
| -1 | -1,552,187 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,552,187.
Example:
1 x 1,552,187 = 1,552,187
and
-1 x -1,552,187 = 1,552,187
Notice both answers equal 1,552,187
With that explanation out of the way, let's continue. Next, we take the number 1,552,187 and divide it by 2:
1,552,187 ÷ 2 = 776,093.5
If the quotient is a whole number, then 2 and 776,093.5 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 | 1,552,187 | |
| -1 | -1,552,187 |
Now, we try dividing 1,552,187 by 3:
1,552,187 ÷ 3 = 517,395.6667
If the quotient is a whole number, then 3 and 517,395.6667 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 | 1,552,187 | |
| -1 | -1,552,187 |
Let's try dividing by 4:
1,552,187 ÷ 4 = 388,046.75
If the quotient is a whole number, then 4 and 388,046.75 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 | 1,552,187 | |
| -1 | 1,552,187 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 91 | 259 | 461 | 481 | 3,227 | 3,367 | 5,993 | 17,057 | 41,951 | 119,399 | 221,741 | 1,552,187 |
| -1 | -7 | -13 | -37 | -91 | -259 | -461 | -481 | -3,227 | -3,367 | -5,993 | -17,057 | -41,951 | -119,399 | -221,741 | -1,552,187 |
