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 26,457,613, 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 | 26,457,613 | |
| -1 | -26,457,613 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,457,613.
Example:
1 x 26,457,613 = 26,457,613
and
-1 x -26,457,613 = 26,457,613
Notice both answers equal 26,457,613
With that explanation out of the way, let's continue. Next, we take the number 26,457,613 and divide it by 2:
26,457,613 ÷ 2 = 13,228,806.5
If the quotient is a whole number, then 2 and 13,228,806.5 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 | 26,457,613 | |
| -1 | -26,457,613 |
Now, we try dividing 26,457,613 by 3:
26,457,613 ÷ 3 = 8,819,204.3333
If the quotient is a whole number, then 3 and 8,819,204.3333 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 | 26,457,613 | |
| -1 | -26,457,613 |
Let's try dividing by 4:
26,457,613 ÷ 4 = 6,614,403.25
If the quotient is a whole number, then 4 and 6,614,403.25 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 | 26,457,613 | |
| -1 | 26,457,613 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 2,093 | 12,641 | 88,487 | 164,333 | 290,743 | 1,150,331 | 2,035,201 | 3,779,659 | 26,457,613 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -2,093 | -12,641 | -88,487 | -164,333 | -290,743 | -1,150,331 | -2,035,201 | -3,779,659 | -26,457,613 |
