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 60,215,089, 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 | 60,215,089 | |
| -1 | -60,215,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,215,089.
Example:
1 x 60,215,089 = 60,215,089
and
-1 x -60,215,089 = 60,215,089
Notice both answers equal 60,215,089
With that explanation out of the way, let's continue. Next, we take the number 60,215,089 and divide it by 2:
60,215,089 ÷ 2 = 30,107,544.5
If the quotient is a whole number, then 2 and 30,107,544.5 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 | 60,215,089 | |
| -1 | -60,215,089 |
Now, we try dividing 60,215,089 by 3:
60,215,089 ÷ 3 = 20,071,696.3333
If the quotient is a whole number, then 3 and 20,071,696.3333 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 | 60,215,089 | |
| -1 | -60,215,089 |
Let's try dividing by 4:
60,215,089 ÷ 4 = 15,053,772.25
If the quotient is a whole number, then 4 and 15,053,772.25 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 | 60,215,089 | |
| -1 | 60,215,089 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 101 | 653 | 913 | 1,111 | 7,183 | 8,383 | 54,199 | 65,953 | 92,213 | 596,189 | 725,483 | 5,474,099 | 60,215,089 |
| -1 | -11 | -83 | -101 | -653 | -913 | -1,111 | -7,183 | -8,383 | -54,199 | -65,953 | -92,213 | -596,189 | -725,483 | -5,474,099 | -60,215,089 |
