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 1,537,135, 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 | 1,537,135 | |
| -1 | -1,537,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,537,135.
Example:
1 x 1,537,135 = 1,537,135
and
-1 x -1,537,135 = 1,537,135
Notice both answers equal 1,537,135
With that explanation out of the way, let's continue. Next, we take the number 1,537,135 and divide it by 2:
1,537,135 ÷ 2 = 768,567.5
If the quotient is a whole number, then 2 and 768,567.5 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 | 1,537,135 | |
| -1 | -1,537,135 |
Now, we try dividing 1,537,135 by 3:
1,537,135 ÷ 3 = 512,378.3333
If the quotient is a whole number, then 3 and 512,378.3333 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 | 1,537,135 | |
| -1 | -1,537,135 |
Let's try dividing by 4:
1,537,135 ÷ 4 = 384,283.75
If the quotient is a whole number, then 4 and 384,283.75 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 | 1,537,135 | |
| -1 | 1,537,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 47 | 155 | 211 | 235 | 1,055 | 1,457 | 6,541 | 7,285 | 9,917 | 32,705 | 49,585 | 307,427 | 1,537,135 |
| -1 | -5 | -31 | -47 | -155 | -211 | -235 | -1,055 | -1,457 | -6,541 | -7,285 | -9,917 | -32,705 | -49,585 | -307,427 | -1,537,135 |
