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 1,363,271, 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 | 1,363,271 | |
| -1 | -1,363,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,363,271.
Example:
1 x 1,363,271 = 1,363,271
and
-1 x -1,363,271 = 1,363,271
Notice both answers equal 1,363,271
With that explanation out of the way, let's continue. Next, we take the number 1,363,271 and divide it by 2:
1,363,271 ÷ 2 = 681,635.5
If the quotient is a whole number, then 2 and 681,635.5 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 | 1,363,271 | |
| -1 | -1,363,271 |
Now, we try dividing 1,363,271 by 3:
1,363,271 ÷ 3 = 454,423.6667
If the quotient is a whole number, then 3 and 454,423.6667 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 | 1,363,271 | |
| -1 | -1,363,271 |
Let's try dividing by 4:
1,363,271 ÷ 4 = 340,817.75
If the quotient is a whole number, then 4 and 340,817.75 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 | 1,363,271 | |
| -1 | 1,363,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 71 | 91 | 211 | 497 | 923 | 1,477 | 2,743 | 6,461 | 14,981 | 19,201 | 104,867 | 194,753 | 1,363,271 |
| -1 | -7 | -13 | -71 | -91 | -211 | -497 | -923 | -1,477 | -2,743 | -6,461 | -14,981 | -19,201 | -104,867 | -194,753 | -1,363,271 |
