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 26,812,513, 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 | 26,812,513 | |
| -1 | -26,812,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,812,513.
Example:
1 x 26,812,513 = 26,812,513
and
-1 x -26,812,513 = 26,812,513
Notice both answers equal 26,812,513
With that explanation out of the way, let's continue. Next, we take the number 26,812,513 and divide it by 2:
26,812,513 ÷ 2 = 13,406,256.5
If the quotient is a whole number, then 2 and 13,406,256.5 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 | 26,812,513 | |
| -1 | -26,812,513 |
Now, we try dividing 26,812,513 by 3:
26,812,513 ÷ 3 = 8,937,504.3333
If the quotient is a whole number, then 3 and 8,937,504.3333 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 | 26,812,513 | |
| -1 | -26,812,513 |
Let's try dividing by 4:
26,812,513 ÷ 4 = 6,703,128.25
If the quotient is a whole number, then 4 and 6,703,128.25 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 | 26,812,513 | |
| -1 | 26,812,513 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 91 | 329 | 611 | 4,277 | 6,269 | 43,883 | 81,497 | 294,643 | 570,479 | 2,062,501 | 3,830,359 | 26,812,513 |
| -1 | -7 | -13 | -47 | -91 | -329 | -611 | -4,277 | -6,269 | -43,883 | -81,497 | -294,643 | -570,479 | -2,062,501 | -3,830,359 | -26,812,513 |
