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 24,401,069, 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 | 24,401,069 | |
| -1 | -24,401,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,401,069.
Example:
1 x 24,401,069 = 24,401,069
and
-1 x -24,401,069 = 24,401,069
Notice both answers equal 24,401,069
With that explanation out of the way, let's continue. Next, we take the number 24,401,069 and divide it by 2:
24,401,069 ÷ 2 = 12,200,534.5
If the quotient is a whole number, then 2 and 12,200,534.5 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 | 24,401,069 | |
| -1 | -24,401,069 |
Now, we try dividing 24,401,069 by 3:
24,401,069 ÷ 3 = 8,133,689.6667
If the quotient is a whole number, then 3 and 8,133,689.6667 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 | 24,401,069 | |
| -1 | -24,401,069 |
Let's try dividing by 4:
24,401,069 ÷ 4 = 6,100,267.25
If the quotient is a whole number, then 4 and 6,100,267.25 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 | 24,401,069 | |
| -1 | 24,401,069 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 49 | 77 | 119 | 187 | 539 | 833 | 1,309 | 2,663 | 9,163 | 18,641 | 29,293 | 45,271 | 130,487 | 205,051 | 316,897 | 497,981 | 1,435,357 | 2,218,279 | 3,485,867 | 24,401,069 |
| -1 | -7 | -11 | -17 | -49 | -77 | -119 | -187 | -539 | -833 | -1,309 | -2,663 | -9,163 | -18,641 | -29,293 | -45,271 | -130,487 | -205,051 | -316,897 | -497,981 | -1,435,357 | -2,218,279 | -3,485,867 | -24,401,069 |
