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 1,887,587, 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 | 1,887,587 | |
| -1 | -1,887,587 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,887,587.
Example:
1 x 1,887,587 = 1,887,587
and
-1 x -1,887,587 = 1,887,587
Notice both answers equal 1,887,587
With that explanation out of the way, let's continue. Next, we take the number 1,887,587 and divide it by 2:
1,887,587 ÷ 2 = 943,793.5
If the quotient is a whole number, then 2 and 943,793.5 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 | 1,887,587 | |
| -1 | -1,887,587 |
Now, we try dividing 1,887,587 by 3:
1,887,587 ÷ 3 = 629,195.6667
If the quotient is a whole number, then 3 and 629,195.6667 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 | 1,887,587 | |
| -1 | -1,887,587 |
Let's try dividing by 4:
1,887,587 ÷ 4 = 471,896.75
If the quotient is a whole number, then 4 and 471,896.75 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 | 1,887,587 | |
| -1 | 1,887,587 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 59 | 107 | 299 | 767 | 1,357 | 1,391 | 2,461 | 6,313 | 17,641 | 31,993 | 82,069 | 145,199 | 1,887,587 |
| -1 | -13 | -23 | -59 | -107 | -299 | -767 | -1,357 | -1,391 | -2,461 | -6,313 | -17,641 | -31,993 | -82,069 | -145,199 | -1,887,587 |
