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 1,271,501, 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 | 1,271,501 | |
| -1 | -1,271,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,271,501.
Example:
1 x 1,271,501 = 1,271,501
and
-1 x -1,271,501 = 1,271,501
Notice both answers equal 1,271,501
With that explanation out of the way, let's continue. Next, we take the number 1,271,501 and divide it by 2:
1,271,501 ÷ 2 = 635,750.5
If the quotient is a whole number, then 2 and 635,750.5 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 | 1,271,501 | |
| -1 | -1,271,501 |
Now, we try dividing 1,271,501 by 3:
1,271,501 ÷ 3 = 423,833.6667
If the quotient is a whole number, then 3 and 423,833.6667 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 | 1,271,501 | |
| -1 | -1,271,501 |
Let's try dividing by 4:
1,271,501 ÷ 4 = 317,875.25
If the quotient is a whole number, then 4 and 317,875.25 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 | 1,271,501 | |
| -1 | 1,271,501 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 337 | 343 | 539 | 2,359 | 3,707 | 3,773 | 16,513 | 25,949 | 115,591 | 181,643 | 1,271,501 |
| -1 | -7 | -11 | -49 | -77 | -337 | -343 | -539 | -2,359 | -3,707 | -3,773 | -16,513 | -25,949 | -115,591 | -181,643 | -1,271,501 |
