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 1,371,097, 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 | 1,371,097 | |
| -1 | -1,371,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,371,097.
Example:
1 x 1,371,097 = 1,371,097
and
-1 x -1,371,097 = 1,371,097
Notice both answers equal 1,371,097
With that explanation out of the way, let's continue. Next, we take the number 1,371,097 and divide it by 2:
1,371,097 ÷ 2 = 685,548.5
If the quotient is a whole number, then 2 and 685,548.5 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 | 1,371,097 | |
| -1 | -1,371,097 |
Now, we try dividing 1,371,097 by 3:
1,371,097 ÷ 3 = 457,032.3333
If the quotient is a whole number, then 3 and 457,032.3333 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 | 1,371,097 | |
| -1 | -1,371,097 |
Let's try dividing by 4:
1,371,097 ÷ 4 = 342,774.25
If the quotient is a whole number, then 4 and 342,774.25 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 | 1,371,097 | |
| -1 | 1,371,097 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 61 | 91 | 133 | 169 | 247 | 427 | 793 | 1,159 | 1,183 | 1,729 | 3,211 | 5,551 | 8,113 | 10,309 | 15,067 | 22,477 | 72,163 | 105,469 | 195,871 | 1,371,097 |
| -1 | -7 | -13 | -19 | -61 | -91 | -133 | -169 | -247 | -427 | -793 | -1,159 | -1,183 | -1,729 | -3,211 | -5,551 | -8,113 | -10,309 | -15,067 | -22,477 | -72,163 | -105,469 | -195,871 | -1,371,097 |
