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 24,021,445, 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 | 24,021,445 | |
| -1 | -24,021,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,021,445.
Example:
1 x 24,021,445 = 24,021,445
and
-1 x -24,021,445 = 24,021,445
Notice both answers equal 24,021,445
With that explanation out of the way, let's continue. Next, we take the number 24,021,445 and divide it by 2:
24,021,445 ÷ 2 = 12,010,722.5
If the quotient is a whole number, then 2 and 12,010,722.5 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 | 24,021,445 | |
| -1 | -24,021,445 |
Now, we try dividing 24,021,445 by 3:
24,021,445 ÷ 3 = 8,007,148.3333
If the quotient is a whole number, then 3 and 8,007,148.3333 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 | 24,021,445 | |
| -1 | -24,021,445 |
Let's try dividing by 4:
24,021,445 ÷ 4 = 6,005,361.25
If the quotient is a whole number, then 4 and 6,005,361.25 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 | 24,021,445 | |
| -1 | 24,021,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 83 | 415 | 581 | 2,905 | 8,269 | 41,345 | 57,883 | 289,415 | 686,327 | 3,431,635 | 4,804,289 | 24,021,445 |
| -1 | -5 | -7 | -35 | -83 | -415 | -581 | -2,905 | -8,269 | -41,345 | -57,883 | -289,415 | -686,327 | -3,431,635 | -4,804,289 | -24,021,445 |
