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 2,554,097, 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 | 2,554,097 | |
| -1 | -2,554,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,554,097.
Example:
1 x 2,554,097 = 2,554,097
and
-1 x -2,554,097 = 2,554,097
Notice both answers equal 2,554,097
With that explanation out of the way, let's continue. Next, we take the number 2,554,097 and divide it by 2:
2,554,097 ÷ 2 = 1,277,048.5
If the quotient is a whole number, then 2 and 1,277,048.5 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 | 2,554,097 | |
| -1 | -2,554,097 |
Now, we try dividing 2,554,097 by 3:
2,554,097 ÷ 3 = 851,365.6667
If the quotient is a whole number, then 3 and 851,365.6667 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 | 2,554,097 | |
| -1 | -2,554,097 |
Let's try dividing by 4:
2,554,097 ÷ 4 = 638,524.25
If the quotient is a whole number, then 4 and 638,524.25 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 | 2,554,097 | |
| -1 | 2,554,097 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 127 | 169 | 221 | 889 | 1,183 | 1,547 | 1,651 | 2,159 | 2,873 | 11,557 | 15,113 | 20,111 | 21,463 | 28,067 | 150,241 | 196,469 | 364,871 | 2,554,097 |
| -1 | -7 | -13 | -17 | -91 | -119 | -127 | -169 | -221 | -889 | -1,183 | -1,547 | -1,651 | -2,159 | -2,873 | -11,557 | -15,113 | -20,111 | -21,463 | -28,067 | -150,241 | -196,469 | -364,871 | -2,554,097 |
