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 60,013,709, 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 | 60,013,709 | |
| -1 | -60,013,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,013,709.
Example:
1 x 60,013,709 = 60,013,709
and
-1 x -60,013,709 = 60,013,709
Notice both answers equal 60,013,709
With that explanation out of the way, let's continue. Next, we take the number 60,013,709 and divide it by 2:
60,013,709 ÷ 2 = 30,006,854.5
If the quotient is a whole number, then 2 and 30,006,854.5 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 | 60,013,709 | |
| -1 | -60,013,709 |
Now, we try dividing 60,013,709 by 3:
60,013,709 ÷ 3 = 20,004,569.6667
If the quotient is a whole number, then 3 and 20,004,569.6667 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 | 60,013,709 | |
| -1 | -60,013,709 |
Let's try dividing by 4:
60,013,709 ÷ 4 = 15,003,427.25
If the quotient is a whole number, then 4 and 15,003,427.25 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 | 60,013,709 | |
| -1 | 60,013,709 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 67 | 287 | 469 | 2,747 | 3,121 | 19,229 | 21,847 | 127,961 | 209,107 | 895,727 | 1,463,749 | 8,573,387 | 60,013,709 |
| -1 | -7 | -41 | -67 | -287 | -469 | -2,747 | -3,121 | -19,229 | -21,847 | -127,961 | -209,107 | -895,727 | -1,463,749 | -8,573,387 | -60,013,709 |
