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 107,060,707, 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 | 107,060,707 | |
| -1 | -107,060,707 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,060,707.
Example:
1 x 107,060,707 = 107,060,707
and
-1 x -107,060,707 = 107,060,707
Notice both answers equal 107,060,707
With that explanation out of the way, let's continue. Next, we take the number 107,060,707 and divide it by 2:
107,060,707 ÷ 2 = 53,530,353.5
If the quotient is a whole number, then 2 and 53,530,353.5 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 | 107,060,707 | |
| -1 | -107,060,707 |
Now, we try dividing 107,060,707 by 3:
107,060,707 ÷ 3 = 35,686,902.3333
If the quotient is a whole number, then 3 and 35,686,902.3333 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 | 107,060,707 | |
| -1 | -107,060,707 |
Let's try dividing by 4:
107,060,707 ÷ 4 = 26,765,176.75
If the quotient is a whole number, then 4 and 26,765,176.75 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 | 107,060,707 | |
| -1 | 107,060,707 |
If you did it right, you will end up with this table:
| 1 | 13 | 67 | 101 | 871 | 1,217 | 1,313 | 6,767 | 15,821 | 81,539 | 87,971 | 122,917 | 1,060,007 | 1,597,921 | 8,235,439 | 107,060,707 |
| -1 | -13 | -67 | -101 | -871 | -1,217 | -1,313 | -6,767 | -15,821 | -81,539 | -87,971 | -122,917 | -1,060,007 | -1,597,921 | -8,235,439 | -107,060,707 |
