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 24,963,197, 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 | 24,963,197 | |
| -1 | -24,963,197 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,963,197.
Example:
1 x 24,963,197 = 24,963,197
and
-1 x -24,963,197 = 24,963,197
Notice both answers equal 24,963,197
With that explanation out of the way, let's continue. Next, we take the number 24,963,197 and divide it by 2:
24,963,197 ÷ 2 = 12,481,598.5
If the quotient is a whole number, then 2 and 12,481,598.5 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 | 24,963,197 | |
| -1 | -24,963,197 |
Now, we try dividing 24,963,197 by 3:
24,963,197 ÷ 3 = 8,321,065.6667
If the quotient is a whole number, then 3 and 8,321,065.6667 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 | 24,963,197 | |
| -1 | -24,963,197 |
Let's try dividing by 4:
24,963,197 ÷ 4 = 6,240,799.25
If the quotient is a whole number, then 4 and 6,240,799.25 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 | 24,963,197 | |
| -1 | 24,963,197 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 49 | 259 | 281 | 343 | 1,813 | 1,967 | 2,401 | 10,397 | 12,691 | 13,769 | 72,779 | 88,837 | 96,383 | 509,453 | 674,681 | 3,566,171 | 24,963,197 |
| -1 | -7 | -37 | -49 | -259 | -281 | -343 | -1,813 | -1,967 | -2,401 | -10,397 | -12,691 | -13,769 | -72,779 | -88,837 | -96,383 | -509,453 | -674,681 | -3,566,171 | -24,963,197 |
