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 60,906,131, 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 | 60,906,131 | |
| -1 | -60,906,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,906,131.
Example:
1 x 60,906,131 = 60,906,131
and
-1 x -60,906,131 = 60,906,131
Notice both answers equal 60,906,131
With that explanation out of the way, let's continue. Next, we take the number 60,906,131 and divide it by 2:
60,906,131 ÷ 2 = 30,453,065.5
If the quotient is a whole number, then 2 and 30,453,065.5 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 | 60,906,131 | |
| -1 | -60,906,131 |
Now, we try dividing 60,906,131 by 3:
60,906,131 ÷ 3 = 20,302,043.6667
If the quotient is a whole number, then 3 and 20,302,043.6667 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 | 60,906,131 | |
| -1 | -60,906,131 |
Let's try dividing by 4:
60,906,131 ÷ 4 = 15,226,532.75
If the quotient is a whole number, then 4 and 15,226,532.75 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 | 60,906,131 | |
| -1 | 60,906,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 101 | 143 | 1,111 | 1,313 | 4,217 | 14,443 | 46,387 | 54,821 | 425,917 | 603,031 | 4,685,087 | 5,536,921 | 60,906,131 |
| -1 | -11 | -13 | -101 | -143 | -1,111 | -1,313 | -4,217 | -14,443 | -46,387 | -54,821 | -425,917 | -603,031 | -4,685,087 | -5,536,921 | -60,906,131 |
