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 2,623,117, 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 | 2,623,117 | |
| -1 | -2,623,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,623,117.
Example:
1 x 2,623,117 = 2,623,117
and
-1 x -2,623,117 = 2,623,117
Notice both answers equal 2,623,117
With that explanation out of the way, let's continue. Next, we take the number 2,623,117 and divide it by 2:
2,623,117 ÷ 2 = 1,311,558.5
If the quotient is a whole number, then 2 and 1,311,558.5 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 | 2,623,117 | |
| -1 | -2,623,117 |
Now, we try dividing 2,623,117 by 3:
2,623,117 ÷ 3 = 874,372.3333
If the quotient is a whole number, then 3 and 874,372.3333 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 | 2,623,117 | |
| -1 | -2,623,117 |
Let's try dividing by 4:
2,623,117 ÷ 4 = 655,779.25
If the quotient is a whole number, then 4 and 655,779.25 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 | 2,623,117 | |
| -1 | 2,623,117 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 47 | 49 | 67 | 119 | 329 | 469 | 799 | 833 | 1,139 | 2,303 | 3,149 | 3,283 | 5,593 | 7,973 | 22,043 | 39,151 | 53,533 | 55,811 | 154,301 | 374,731 | 2,623,117 |
| -1 | -7 | -17 | -47 | -49 | -67 | -119 | -329 | -469 | -799 | -833 | -1,139 | -2,303 | -3,149 | -3,283 | -5,593 | -7,973 | -22,043 | -39,151 | -53,533 | -55,811 | -154,301 | -374,731 | -2,623,117 |
