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 1,587,775, 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 | 1,587,775 | |
| -1 | -1,587,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,587,775.
Example:
1 x 1,587,775 = 1,587,775
and
-1 x -1,587,775 = 1,587,775
Notice both answers equal 1,587,775
With that explanation out of the way, let's continue. Next, we take the number 1,587,775 and divide it by 2:
1,587,775 ÷ 2 = 793,887.5
If the quotient is a whole number, then 2 and 793,887.5 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 | 1,587,775 | |
| -1 | -1,587,775 |
Now, we try dividing 1,587,775 by 3:
1,587,775 ÷ 3 = 529,258.3333
If the quotient is a whole number, then 3 and 529,258.3333 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 | 1,587,775 | |
| -1 | -1,587,775 |
Let's try dividing by 4:
1,587,775 ÷ 4 = 396,943.75
If the quotient is a whole number, then 4 and 396,943.75 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 | 1,587,775 | |
| -1 | 1,587,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 43 | 175 | 211 | 215 | 301 | 1,055 | 1,075 | 1,477 | 1,505 | 5,275 | 7,385 | 7,525 | 9,073 | 36,925 | 45,365 | 63,511 | 226,825 | 317,555 | 1,587,775 |
| -1 | -5 | -7 | -25 | -35 | -43 | -175 | -211 | -215 | -301 | -1,055 | -1,075 | -1,477 | -1,505 | -5,275 | -7,385 | -7,525 | -9,073 | -36,925 | -45,365 | -63,511 | -226,825 | -317,555 | -1,587,775 |
