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 24,837,527, 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 | 24,837,527 | |
| -1 | -24,837,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,837,527.
Example:
1 x 24,837,527 = 24,837,527
and
-1 x -24,837,527 = 24,837,527
Notice both answers equal 24,837,527
With that explanation out of the way, let's continue. Next, we take the number 24,837,527 and divide it by 2:
24,837,527 ÷ 2 = 12,418,763.5
If the quotient is a whole number, then 2 and 12,418,763.5 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 | 24,837,527 | |
| -1 | -24,837,527 |
Now, we try dividing 24,837,527 by 3:
24,837,527 ÷ 3 = 8,279,175.6667
If the quotient is a whole number, then 3 and 8,279,175.6667 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 | 24,837,527 | |
| -1 | -24,837,527 |
Let's try dividing by 4:
24,837,527 ÷ 4 = 6,209,381.75
If the quotient is a whole number, then 4 and 6,209,381.75 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 | 24,837,527 | |
| -1 | 24,837,527 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 289 | 601 | 2,431 | 3,179 | 3,757 | 6,611 | 7,813 | 10,217 | 41,327 | 85,943 | 112,387 | 132,821 | 173,689 | 1,461,031 | 1,910,579 | 2,257,957 | 24,837,527 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -289 | -601 | -2,431 | -3,179 | -3,757 | -6,611 | -7,813 | -10,217 | -41,327 | -85,943 | -112,387 | -132,821 | -173,689 | -1,461,031 | -1,910,579 | -2,257,957 | -24,837,527 |
