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 43,637,215, 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 | 43,637,215 | |
| -1 | -43,637,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,637,215.
Example:
1 x 43,637,215 = 43,637,215
and
-1 x -43,637,215 = 43,637,215
Notice both answers equal 43,637,215
With that explanation out of the way, let's continue. Next, we take the number 43,637,215 and divide it by 2:
43,637,215 ÷ 2 = 21,818,607.5
If the quotient is a whole number, then 2 and 21,818,607.5 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 | 43,637,215 | |
| -1 | -43,637,215 |
Now, we try dividing 43,637,215 by 3:
43,637,215 ÷ 3 = 14,545,738.3333
If the quotient is a whole number, then 3 and 14,545,738.3333 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 | 43,637,215 | |
| -1 | -43,637,215 |
Let's try dividing by 4:
43,637,215 ÷ 4 = 10,909,303.75
If the quotient is a whole number, then 4 and 10,909,303.75 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 | 43,637,215 | |
| -1 | 43,637,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 349 | 1,471 | 1,745 | 5,933 | 7,355 | 25,007 | 29,665 | 125,035 | 513,379 | 2,566,895 | 8,727,443 | 43,637,215 |
| -1 | -5 | -17 | -85 | -349 | -1,471 | -1,745 | -5,933 | -7,355 | -25,007 | -29,665 | -125,035 | -513,379 | -2,566,895 | -8,727,443 | -43,637,215 |
