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 1,571,945, 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 | 1,571,945 | |
| -1 | -1,571,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,571,945.
Example:
1 x 1,571,945 = 1,571,945
and
-1 x -1,571,945 = 1,571,945
Notice both answers equal 1,571,945
With that explanation out of the way, let's continue. Next, we take the number 1,571,945 and divide it by 2:
1,571,945 ÷ 2 = 785,972.5
If the quotient is a whole number, then 2 and 785,972.5 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 | 1,571,945 | |
| -1 | -1,571,945 |
Now, we try dividing 1,571,945 by 3:
1,571,945 ÷ 3 = 523,981.6667
If the quotient is a whole number, then 3 and 523,981.6667 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 | 1,571,945 | |
| -1 | -1,571,945 |
Let's try dividing by 4:
1,571,945 ÷ 4 = 392,986.25
If the quotient is a whole number, then 4 and 392,986.25 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 | 1,571,945 | |
| -1 | 1,571,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 37 | 145 | 185 | 293 | 1,073 | 1,465 | 5,365 | 8,497 | 10,841 | 42,485 | 54,205 | 314,389 | 1,571,945 |
| -1 | -5 | -29 | -37 | -145 | -185 | -293 | -1,073 | -1,465 | -5,365 | -8,497 | -10,841 | -42,485 | -54,205 | -314,389 | -1,571,945 |
