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 23,214,355, 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 | 23,214,355 | |
| -1 | -23,214,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,214,355.
Example:
1 x 23,214,355 = 23,214,355
and
-1 x -23,214,355 = 23,214,355
Notice both answers equal 23,214,355
With that explanation out of the way, let's continue. Next, we take the number 23,214,355 and divide it by 2:
23,214,355 ÷ 2 = 11,607,177.5
If the quotient is a whole number, then 2 and 11,607,177.5 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 | 23,214,355 | |
| -1 | -23,214,355 |
Now, we try dividing 23,214,355 by 3:
23,214,355 ÷ 3 = 7,738,118.3333
If the quotient is a whole number, then 3 and 7,738,118.3333 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 | 23,214,355 | |
| -1 | -23,214,355 |
Let's try dividing by 4:
23,214,355 ÷ 4 = 5,803,588.75
If the quotient is a whole number, then 4 and 5,803,588.75 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 | 23,214,355 | |
| -1 | 23,214,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 37 | 145 | 185 | 1,073 | 4,327 | 5,365 | 21,635 | 125,483 | 160,099 | 627,415 | 800,495 | 4,642,871 | 23,214,355 |
| -1 | -5 | -29 | -37 | -145 | -185 | -1,073 | -4,327 | -5,365 | -21,635 | -125,483 | -160,099 | -627,415 | -800,495 | -4,642,871 | -23,214,355 |
