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 126,473,711, 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 | 126,473,711 | |
| -1 | -126,473,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 126,473,711.
Example:
1 x 126,473,711 = 126,473,711
and
-1 x -126,473,711 = 126,473,711
Notice both answers equal 126,473,711
With that explanation out of the way, let's continue. Next, we take the number 126,473,711 and divide it by 2:
126,473,711 ÷ 2 = 63,236,855.5
If the quotient is a whole number, then 2 and 63,236,855.5 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 | 126,473,711 | |
| -1 | -126,473,711 |
Now, we try dividing 126,473,711 by 3:
126,473,711 ÷ 3 = 42,157,903.6667
If the quotient is a whole number, then 3 and 42,157,903.6667 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 | 126,473,711 | |
| -1 | -126,473,711 |
Let's try dividing by 4:
126,473,711 ÷ 4 = 31,618,427.75
If the quotient is a whole number, then 4 and 31,618,427.75 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 | 126,473,711 | |
| -1 | 126,473,711 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 2,093 | 60,427 | 422,989 | 785,551 | 1,389,821 | 5,498,857 | 9,728,747 | 18,067,673 | 126,473,711 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -2,093 | -60,427 | -422,989 | -785,551 | -1,389,821 | -5,498,857 | -9,728,747 | -18,067,673 | -126,473,711 |
