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 1,571,075, 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 | 1,571,075 | |
| -1 | -1,571,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,571,075.
Example:
1 x 1,571,075 = 1,571,075
and
-1 x -1,571,075 = 1,571,075
Notice both answers equal 1,571,075
With that explanation out of the way, let's continue. Next, we take the number 1,571,075 and divide it by 2:
1,571,075 ÷ 2 = 785,537.5
If the quotient is a whole number, then 2 and 785,537.5 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 | 1,571,075 | |
| -1 | -1,571,075 |
Now, we try dividing 1,571,075 by 3:
1,571,075 ÷ 3 = 523,691.6667
If the quotient is a whole number, then 3 and 523,691.6667 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 | 1,571,075 | |
| -1 | -1,571,075 |
Let's try dividing by 4:
1,571,075 ÷ 4 = 392,768.75
If the quotient is a whole number, then 4 and 392,768.75 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 | 1,571,075 | |
| -1 | 1,571,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 29 | 55 | 145 | 197 | 275 | 319 | 725 | 985 | 1,595 | 2,167 | 4,925 | 5,713 | 7,975 | 10,835 | 28,565 | 54,175 | 62,843 | 142,825 | 314,215 | 1,571,075 |
| -1 | -5 | -11 | -25 | -29 | -55 | -145 | -197 | -275 | -319 | -725 | -985 | -1,595 | -2,167 | -4,925 | -5,713 | -7,975 | -10,835 | -28,565 | -54,175 | -62,843 | -142,825 | -314,215 | -1,571,075 |
