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 1,557,325, 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 | 1,557,325 | |
| -1 | -1,557,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,557,325.
Example:
1 x 1,557,325 = 1,557,325
and
-1 x -1,557,325 = 1,557,325
Notice both answers equal 1,557,325
With that explanation out of the way, let's continue. Next, we take the number 1,557,325 and divide it by 2:
1,557,325 ÷ 2 = 778,662.5
If the quotient is a whole number, then 2 and 778,662.5 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 | 1,557,325 | |
| -1 | -1,557,325 |
Now, we try dividing 1,557,325 by 3:
1,557,325 ÷ 3 = 519,108.3333
If the quotient is a whole number, then 3 and 519,108.3333 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 | 1,557,325 | |
| -1 | -1,557,325 |
Let's try dividing by 4:
1,557,325 ÷ 4 = 389,331.25
If the quotient is a whole number, then 4 and 389,331.25 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 | 1,557,325 | |
| -1 | 1,557,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 809 | 1,925 | 4,045 | 5,663 | 8,899 | 20,225 | 28,315 | 44,495 | 62,293 | 141,575 | 222,475 | 311,465 | 1,557,325 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -809 | -1,925 | -4,045 | -5,663 | -8,899 | -20,225 | -28,315 | -44,495 | -62,293 | -141,575 | -222,475 | -311,465 | -1,557,325 |
