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 24,243,415, 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 | 24,243,415 | |
| -1 | -24,243,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,243,415.
Example:
1 x 24,243,415 = 24,243,415
and
-1 x -24,243,415 = 24,243,415
Notice both answers equal 24,243,415
With that explanation out of the way, let's continue. Next, we take the number 24,243,415 and divide it by 2:
24,243,415 ÷ 2 = 12,121,707.5
If the quotient is a whole number, then 2 and 12,121,707.5 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 | 24,243,415 | |
| -1 | -24,243,415 |
Now, we try dividing 24,243,415 by 3:
24,243,415 ÷ 3 = 8,081,138.3333
If the quotient is a whole number, then 3 and 8,081,138.3333 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 | 24,243,415 | |
| -1 | -24,243,415 |
Let's try dividing by 4:
24,243,415 ÷ 4 = 6,060,853.75
If the quotient is a whole number, then 4 and 6,060,853.75 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 | 24,243,415 | |
| -1 | 24,243,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 313 | 1,565 | 2,191 | 2,213 | 10,955 | 11,065 | 15,491 | 77,455 | 692,669 | 3,463,345 | 4,848,683 | 24,243,415 |
| -1 | -5 | -7 | -35 | -313 | -1,565 | -2,191 | -2,213 | -10,955 | -11,065 | -15,491 | -77,455 | -692,669 | -3,463,345 | -4,848,683 | -24,243,415 |
