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 43,821,271, 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 | 43,821,271 | |
| -1 | -43,821,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,821,271.
Example:
1 x 43,821,271 = 43,821,271
and
-1 x -43,821,271 = 43,821,271
Notice both answers equal 43,821,271
With that explanation out of the way, let's continue. Next, we take the number 43,821,271 and divide it by 2:
43,821,271 ÷ 2 = 21,910,635.5
If the quotient is a whole number, then 2 and 21,910,635.5 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 | 43,821,271 | |
| -1 | -43,821,271 |
Now, we try dividing 43,821,271 by 3:
43,821,271 ÷ 3 = 14,607,090.3333
If the quotient is a whole number, then 3 and 14,607,090.3333 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 | 43,821,271 | |
| -1 | -43,821,271 |
Let's try dividing by 4:
43,821,271 ÷ 4 = 10,955,317.75
If the quotient is a whole number, then 4 and 10,955,317.75 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 | 43,821,271 | |
| -1 | 43,821,271 |
If you did it right, you will end up with this table:
| 1 | 13 | 71 | 197 | 241 | 923 | 2,561 | 3,133 | 13,987 | 17,111 | 47,477 | 181,831 | 222,443 | 617,201 | 3,370,867 | 43,821,271 |
| -1 | -13 | -71 | -197 | -241 | -923 | -2,561 | -3,133 | -13,987 | -17,111 | -47,477 | -181,831 | -222,443 | -617,201 | -3,370,867 | -43,821,271 |
