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 25,822,643, 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 | 25,822,643 | |
| -1 | -25,822,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,822,643.
Example:
1 x 25,822,643 = 25,822,643
and
-1 x -25,822,643 = 25,822,643
Notice both answers equal 25,822,643
With that explanation out of the way, let's continue. Next, we take the number 25,822,643 and divide it by 2:
25,822,643 ÷ 2 = 12,911,321.5
If the quotient is a whole number, then 2 and 12,911,321.5 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 | 25,822,643 | |
| -1 | -25,822,643 |
Now, we try dividing 25,822,643 by 3:
25,822,643 ÷ 3 = 8,607,547.6667
If the quotient is a whole number, then 3 and 8,607,547.6667 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 | 25,822,643 | |
| -1 | -25,822,643 |
Let's try dividing by 4:
25,822,643 ÷ 4 = 6,455,660.75
If the quotient is a whole number, then 4 and 6,455,660.75 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 | 25,822,643 | |
| -1 | 25,822,643 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 19,727 | 138,089 | 216,997 | 335,359 | 1,518,979 | 2,347,513 | 3,688,949 | 25,822,643 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -19,727 | -138,089 | -216,997 | -335,359 | -1,518,979 | -2,347,513 | -3,688,949 | -25,822,643 |
