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 24,143,203, 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 | 24,143,203 | |
| -1 | -24,143,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,143,203.
Example:
1 x 24,143,203 = 24,143,203
and
-1 x -24,143,203 = 24,143,203
Notice both answers equal 24,143,203
With that explanation out of the way, let's continue. Next, we take the number 24,143,203 and divide it by 2:
24,143,203 ÷ 2 = 12,071,601.5
If the quotient is a whole number, then 2 and 12,071,601.5 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 | 24,143,203 | |
| -1 | -24,143,203 |
Now, we try dividing 24,143,203 by 3:
24,143,203 ÷ 3 = 8,047,734.3333
If the quotient is a whole number, then 3 and 8,047,734.3333 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 | 24,143,203 | |
| -1 | -24,143,203 |
Let's try dividing by 4:
24,143,203 ÷ 4 = 6,035,800.75
If the quotient is a whole number, then 4 and 6,035,800.75 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 | 24,143,203 | |
| -1 | 24,143,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 37 | 97 | 217 | 259 | 679 | 961 | 1,147 | 3,007 | 3,589 | 6,727 | 8,029 | 21,049 | 25,123 | 35,557 | 93,217 | 111,259 | 248,899 | 652,519 | 778,813 | 3,449,029 | 24,143,203 |
| -1 | -7 | -31 | -37 | -97 | -217 | -259 | -679 | -961 | -1,147 | -3,007 | -3,589 | -6,727 | -8,029 | -21,049 | -25,123 | -35,557 | -93,217 | -111,259 | -248,899 | -652,519 | -778,813 | -3,449,029 | -24,143,203 |
