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 60,221,203, 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 | 60,221,203 | |
| -1 | -60,221,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,221,203.
Example:
1 x 60,221,203 = 60,221,203
and
-1 x -60,221,203 = 60,221,203
Notice both answers equal 60,221,203
With that explanation out of the way, let's continue. Next, we take the number 60,221,203 and divide it by 2:
60,221,203 ÷ 2 = 30,110,601.5
If the quotient is a whole number, then 2 and 30,110,601.5 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 | 60,221,203 | |
| -1 | -60,221,203 |
Now, we try dividing 60,221,203 by 3:
60,221,203 ÷ 3 = 20,073,734.3333
If the quotient is a whole number, then 3 and 20,073,734.3333 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 | 60,221,203 | |
| -1 | -60,221,203 |
Let's try dividing by 4:
60,221,203 ÷ 4 = 15,055,300.75
If the quotient is a whole number, then 4 and 15,055,300.75 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 | 60,221,203 | |
| -1 | 60,221,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 113 | 133 | 791 | 2,147 | 4,007 | 15,029 | 28,049 | 76,133 | 452,791 | 532,931 | 3,169,537 | 8,603,029 | 60,221,203 |
| -1 | -7 | -19 | -113 | -133 | -791 | -2,147 | -4,007 | -15,029 | -28,049 | -76,133 | -452,791 | -532,931 | -3,169,537 | -8,603,029 | -60,221,203 |
