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 21,941,629, 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 | 21,941,629 | |
| -1 | -21,941,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,941,629.
Example:
1 x 21,941,629 = 21,941,629
and
-1 x -21,941,629 = 21,941,629
Notice both answers equal 21,941,629
With that explanation out of the way, let's continue. Next, we take the number 21,941,629 and divide it by 2:
21,941,629 ÷ 2 = 10,970,814.5
If the quotient is a whole number, then 2 and 10,970,814.5 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 | 21,941,629 | |
| -1 | -21,941,629 |
Now, we try dividing 21,941,629 by 3:
21,941,629 ÷ 3 = 7,313,876.3333
If the quotient is a whole number, then 3 and 7,313,876.3333 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 | 21,941,629 | |
| -1 | -21,941,629 |
Let's try dividing by 4:
21,941,629 ÷ 4 = 5,485,407.25
If the quotient is a whole number, then 4 and 5,485,407.25 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 | 21,941,629 | |
| -1 | 21,941,629 |
If you did it right, you will end up with this table:
| 1 | 37 | 53 | 67 | 167 | 1,961 | 2,479 | 3,551 | 6,179 | 8,851 | 11,189 | 131,387 | 327,487 | 413,993 | 593,017 | 21,941,629 |
| -1 | -37 | -53 | -67 | -167 | -1,961 | -2,479 | -3,551 | -6,179 | -8,851 | -11,189 | -131,387 | -327,487 | -413,993 | -593,017 | -21,941,629 |
