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 126,573,811, 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 | 126,573,811 | |
| -1 | -126,573,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 126,573,811.
Example:
1 x 126,573,811 = 126,573,811
and
-1 x -126,573,811 = 126,573,811
Notice both answers equal 126,573,811
With that explanation out of the way, let's continue. Next, we take the number 126,573,811 and divide it by 2:
126,573,811 ÷ 2 = 63,286,905.5
If the quotient is a whole number, then 2 and 63,286,905.5 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 | 126,573,811 | |
| -1 | -126,573,811 |
Now, we try dividing 126,573,811 by 3:
126,573,811 ÷ 3 = 42,191,270.3333
If the quotient is a whole number, then 3 and 42,191,270.3333 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 | 126,573,811 | |
| -1 | -126,573,811 |
Let's try dividing by 4:
126,573,811 ÷ 4 = 31,643,452.75
If the quotient is a whole number, then 4 and 31,643,452.75 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 | 126,573,811 | |
| -1 | 126,573,811 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 49 | 91 | 301 | 559 | 637 | 2,107 | 3,913 | 4,621 | 27,391 | 32,347 | 60,073 | 198,703 | 226,429 | 420,511 | 1,390,921 | 2,583,139 | 2,943,577 | 9,736,447 | 18,081,973 | 126,573,811 |
| -1 | -7 | -13 | -43 | -49 | -91 | -301 | -559 | -637 | -2,107 | -3,913 | -4,621 | -27,391 | -32,347 | -60,073 | -198,703 | -226,429 | -420,511 | -1,390,921 | -2,583,139 | -2,943,577 | -9,736,447 | -18,081,973 | -126,573,811 |
