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 43,042,097, 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 | 43,042,097 | |
| -1 | -43,042,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,042,097.
Example:
1 x 43,042,097 = 43,042,097
and
-1 x -43,042,097 = 43,042,097
Notice both answers equal 43,042,097
With that explanation out of the way, let's continue. Next, we take the number 43,042,097 and divide it by 2:
43,042,097 ÷ 2 = 21,521,048.5
If the quotient is a whole number, then 2 and 21,521,048.5 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 | 43,042,097 | |
| -1 | -43,042,097 |
Now, we try dividing 43,042,097 by 3:
43,042,097 ÷ 3 = 14,347,365.6667
If the quotient is a whole number, then 3 and 14,347,365.6667 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 | 43,042,097 | |
| -1 | -43,042,097 |
Let's try dividing by 4:
43,042,097 ÷ 4 = 10,760,524.25
If the quotient is a whole number, then 4 and 10,760,524.25 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 | 43,042,097 | |
| -1 | 43,042,097 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 151 | 301 | 947 | 1,057 | 6,493 | 6,629 | 40,721 | 45,451 | 142,997 | 285,047 | 1,000,979 | 6,148,871 | 43,042,097 |
| -1 | -7 | -43 | -151 | -301 | -947 | -1,057 | -6,493 | -6,629 | -40,721 | -45,451 | -142,997 | -285,047 | -1,000,979 | -6,148,871 | -43,042,097 |
