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 24,261,839, 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 | 24,261,839 | |
| -1 | -24,261,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,261,839.
Example:
1 x 24,261,839 = 24,261,839
and
-1 x -24,261,839 = 24,261,839
Notice both answers equal 24,261,839
With that explanation out of the way, let's continue. Next, we take the number 24,261,839 and divide it by 2:
24,261,839 ÷ 2 = 12,130,919.5
If the quotient is a whole number, then 2 and 12,130,919.5 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 | 24,261,839 | |
| -1 | -24,261,839 |
Now, we try dividing 24,261,839 by 3:
24,261,839 ÷ 3 = 8,087,279.6667
If the quotient is a whole number, then 3 and 8,087,279.6667 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 | 24,261,839 | |
| -1 | -24,261,839 |
Let's try dividing by 4:
24,261,839 ÷ 4 = 6,065,459.75
If the quotient is a whole number, then 4 and 6,065,459.75 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 | 24,261,839 | |
| -1 | 24,261,839 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 67 | 119 | 179 | 289 | 469 | 1,139 | 1,253 | 2,023 | 3,043 | 7,973 | 11,993 | 19,363 | 21,301 | 51,731 | 83,951 | 135,541 | 203,881 | 362,117 | 1,427,167 | 3,465,977 | 24,261,839 |
| -1 | -7 | -17 | -67 | -119 | -179 | -289 | -469 | -1,139 | -1,253 | -2,023 | -3,043 | -7,973 | -11,993 | -19,363 | -21,301 | -51,731 | -83,951 | -135,541 | -203,881 | -362,117 | -1,427,167 | -3,465,977 | -24,261,839 |
