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 1,537,745, 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 | 1,537,745 | |
| -1 | -1,537,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,537,745.
Example:
1 x 1,537,745 = 1,537,745
and
-1 x -1,537,745 = 1,537,745
Notice both answers equal 1,537,745
With that explanation out of the way, let's continue. Next, we take the number 1,537,745 and divide it by 2:
1,537,745 ÷ 2 = 768,872.5
If the quotient is a whole number, then 2 and 768,872.5 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 | 1,537,745 | |
| -1 | -1,537,745 |
Now, we try dividing 1,537,745 by 3:
1,537,745 ÷ 3 = 512,581.6667
If the quotient is a whole number, then 3 and 512,581.6667 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 | 1,537,745 | |
| -1 | -1,537,745 |
Let's try dividing by 4:
1,537,745 ÷ 4 = 384,436.25
If the quotient is a whole number, then 4 and 384,436.25 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 | 1,537,745 | |
| -1 | 1,537,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 73 | 365 | 383 | 803 | 1,915 | 4,015 | 4,213 | 21,065 | 27,959 | 139,795 | 307,549 | 1,537,745 |
| -1 | -5 | -11 | -55 | -73 | -365 | -383 | -803 | -1,915 | -4,015 | -4,213 | -21,065 | -27,959 | -139,795 | -307,549 | -1,537,745 |
