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 43,251,233, 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 | 43,251,233 | |
| -1 | -43,251,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,251,233.
Example:
1 x 43,251,233 = 43,251,233
and
-1 x -43,251,233 = 43,251,233
Notice both answers equal 43,251,233
With that explanation out of the way, let's continue. Next, we take the number 43,251,233 and divide it by 2:
43,251,233 ÷ 2 = 21,625,616.5
If the quotient is a whole number, then 2 and 21,625,616.5 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 | 43,251,233 | |
| -1 | -43,251,233 |
Now, we try dividing 43,251,233 by 3:
43,251,233 ÷ 3 = 14,417,077.6667
If the quotient is a whole number, then 3 and 14,417,077.6667 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 | 43,251,233 | |
| -1 | -43,251,233 |
Let's try dividing by 4:
43,251,233 ÷ 4 = 10,812,808.25
If the quotient is a whole number, then 4 and 10,812,808.25 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 | 43,251,233 | |
| -1 | 43,251,233 |
If you did it right, you will end up with this table:
| 1 | 47 | 53 | 97 | 179 | 2,491 | 4,559 | 5,141 | 8,413 | 9,487 | 17,363 | 241,627 | 445,889 | 816,061 | 920,239 | 43,251,233 |
| -1 | -47 | -53 | -97 | -179 | -2,491 | -4,559 | -5,141 | -8,413 | -9,487 | -17,363 | -241,627 | -445,889 | -816,061 | -920,239 | -43,251,233 |
