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 24,123,407, 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 | 24,123,407 | |
| -1 | -24,123,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,123,407.
Example:
1 x 24,123,407 = 24,123,407
and
-1 x -24,123,407 = 24,123,407
Notice both answers equal 24,123,407
With that explanation out of the way, let's continue. Next, we take the number 24,123,407 and divide it by 2:
24,123,407 ÷ 2 = 12,061,703.5
If the quotient is a whole number, then 2 and 12,061,703.5 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 | 24,123,407 | |
| -1 | -24,123,407 |
Now, we try dividing 24,123,407 by 3:
24,123,407 ÷ 3 = 8,041,135.6667
If the quotient is a whole number, then 3 and 8,041,135.6667 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 | 24,123,407 | |
| -1 | -24,123,407 |
Let's try dividing by 4:
24,123,407 ÷ 4 = 6,030,851.75
If the quotient is a whole number, then 4 and 6,030,851.75 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 | 24,123,407 | |
| -1 | 24,123,407 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 121 | 133 | 209 | 847 | 1,463 | 1,499 | 2,299 | 10,493 | 16,093 | 16,489 | 28,481 | 115,423 | 181,379 | 199,367 | 313,291 | 1,269,653 | 2,193,037 | 3,446,201 | 24,123,407 |
| -1 | -7 | -11 | -19 | -77 | -121 | -133 | -209 | -847 | -1,463 | -1,499 | -2,299 | -10,493 | -16,093 | -16,489 | -28,481 | -115,423 | -181,379 | -199,367 | -313,291 | -1,269,653 | -2,193,037 | -3,446,201 | -24,123,407 |
