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 1,140,503, 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 | 1,140,503 | |
| -1 | -1,140,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,140,503.
Example:
1 x 1,140,503 = 1,140,503
and
-1 x -1,140,503 = 1,140,503
Notice both answers equal 1,140,503
With that explanation out of the way, let's continue. Next, we take the number 1,140,503 and divide it by 2:
1,140,503 ÷ 2 = 570,251.5
If the quotient is a whole number, then 2 and 570,251.5 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 | 1,140,503 | |
| -1 | -1,140,503 |
Now, we try dividing 1,140,503 by 3:
1,140,503 ÷ 3 = 380,167.6667
If the quotient is a whole number, then 3 and 380,167.6667 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 | 1,140,503 | |
| -1 | -1,140,503 |
Let's try dividing by 4:
1,140,503 ÷ 4 = 285,125.75
If the quotient is a whole number, then 4 and 285,125.75 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 | 1,140,503 | |
| -1 | 1,140,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 83 | 91 | 151 | 581 | 1,057 | 1,079 | 1,963 | 7,553 | 12,533 | 13,741 | 87,731 | 162,929 | 1,140,503 |
| -1 | -7 | -13 | -83 | -91 | -151 | -581 | -1,057 | -1,079 | -1,963 | -7,553 | -12,533 | -13,741 | -87,731 | -162,929 | -1,140,503 |
