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 1,587,773, 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 | 1,587,773 | |
| -1 | -1,587,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,587,773.
Example:
1 x 1,587,773 = 1,587,773
and
-1 x -1,587,773 = 1,587,773
Notice both answers equal 1,587,773
With that explanation out of the way, let's continue. Next, we take the number 1,587,773 and divide it by 2:
1,587,773 ÷ 2 = 793,886.5
If the quotient is a whole number, then 2 and 793,886.5 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 | 1,587,773 | |
| -1 | -1,587,773 |
Now, we try dividing 1,587,773 by 3:
1,587,773 ÷ 3 = 529,257.6667
If the quotient is a whole number, then 3 and 529,257.6667 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 | 1,587,773 | |
| -1 | -1,587,773 |
Let's try dividing by 4:
1,587,773 ÷ 4 = 396,943.25
If the quotient is a whole number, then 4 and 396,943.25 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 | 1,587,773 | |
| -1 | 1,587,773 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 71 | 107 | 209 | 781 | 1,177 | 1,349 | 2,033 | 7,597 | 14,839 | 22,363 | 83,567 | 144,343 | 1,587,773 |
| -1 | -11 | -19 | -71 | -107 | -209 | -781 | -1,177 | -1,349 | -2,033 | -7,597 | -14,839 | -22,363 | -83,567 | -144,343 | -1,587,773 |
