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 1,572,065, 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 | 1,572,065 | |
| -1 | -1,572,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,572,065.
Example:
1 x 1,572,065 = 1,572,065
and
-1 x -1,572,065 = 1,572,065
Notice both answers equal 1,572,065
With that explanation out of the way, let's continue. Next, we take the number 1,572,065 and divide it by 2:
1,572,065 ÷ 2 = 786,032.5
If the quotient is a whole number, then 2 and 786,032.5 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 | 1,572,065 | |
| -1 | -1,572,065 |
Now, we try dividing 1,572,065 by 3:
1,572,065 ÷ 3 = 524,021.6667
If the quotient is a whole number, then 3 and 524,021.6667 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 | 1,572,065 | |
| -1 | -1,572,065 |
Let's try dividing by 4:
1,572,065 ÷ 4 = 393,016.25
If the quotient is a whole number, then 4 and 393,016.25 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 | 1,572,065 | |
| -1 | 1,572,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 283 | 505 | 1,111 | 1,415 | 3,113 | 5,555 | 15,565 | 28,583 | 142,915 | 314,413 | 1,572,065 |
| -1 | -5 | -11 | -55 | -101 | -283 | -505 | -1,111 | -1,415 | -3,113 | -5,555 | -15,565 | -28,583 | -142,915 | -314,413 | -1,572,065 |
