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 60,071,215, 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 | 60,071,215 | |
| -1 | -60,071,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,071,215.
Example:
1 x 60,071,215 = 60,071,215
and
-1 x -60,071,215 = 60,071,215
Notice both answers equal 60,071,215
With that explanation out of the way, let's continue. Next, we take the number 60,071,215 and divide it by 2:
60,071,215 ÷ 2 = 30,035,607.5
If the quotient is a whole number, then 2 and 30,035,607.5 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 | 60,071,215 | |
| -1 | -60,071,215 |
Now, we try dividing 60,071,215 by 3:
60,071,215 ÷ 3 = 20,023,738.3333
If the quotient is a whole number, then 3 and 20,023,738.3333 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 | 60,071,215 | |
| -1 | -60,071,215 |
Let's try dividing by 4:
60,071,215 ÷ 4 = 15,017,803.75
If the quotient is a whole number, then 4 and 15,017,803.75 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 | 60,071,215 | |
| -1 | 60,071,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 271 | 1,031 | 1,355 | 5,155 | 11,653 | 44,333 | 58,265 | 221,665 | 279,401 | 1,397,005 | 12,014,243 | 60,071,215 |
| -1 | -5 | -43 | -215 | -271 | -1,031 | -1,355 | -5,155 | -11,653 | -44,333 | -58,265 | -221,665 | -279,401 | -1,397,005 | -12,014,243 | -60,071,215 |
