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 126,235,601, 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 | 126,235,601 | |
| -1 | -126,235,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 126,235,601.
Example:
1 x 126,235,601 = 126,235,601
and
-1 x -126,235,601 = 126,235,601
Notice both answers equal 126,235,601
With that explanation out of the way, let's continue. Next, we take the number 126,235,601 and divide it by 2:
126,235,601 ÷ 2 = 63,117,800.5
If the quotient is a whole number, then 2 and 63,117,800.5 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 | 126,235,601 | |
| -1 | -126,235,601 |
Now, we try dividing 126,235,601 by 3:
126,235,601 ÷ 3 = 42,078,533.6667
If the quotient is a whole number, then 3 and 42,078,533.6667 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 | 126,235,601 | |
| -1 | -126,235,601 |
Let's try dividing by 4:
126,235,601 ÷ 4 = 31,558,900.25
If the quotient is a whole number, then 4 and 31,558,900.25 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 | 126,235,601 | |
| -1 | 126,235,601 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 79 | 703 | 1,501 | 2,273 | 2,923 | 43,187 | 55,537 | 84,101 | 179,567 | 1,597,919 | 3,411,773 | 6,643,979 | 126,235,601 |
| -1 | -19 | -37 | -79 | -703 | -1,501 | -2,273 | -2,923 | -43,187 | -55,537 | -84,101 | -179,567 | -1,597,919 | -3,411,773 | -6,643,979 | -126,235,601 |
