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 107,456,219, 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 | 107,456,219 | |
| -1 | -107,456,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,456,219.
Example:
1 x 107,456,219 = 107,456,219
and
-1 x -107,456,219 = 107,456,219
Notice both answers equal 107,456,219
With that explanation out of the way, let's continue. Next, we take the number 107,456,219 and divide it by 2:
107,456,219 ÷ 2 = 53,728,109.5
If the quotient is a whole number, then 2 and 53,728,109.5 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 | 107,456,219 | |
| -1 | -107,456,219 |
Now, we try dividing 107,456,219 by 3:
107,456,219 ÷ 3 = 35,818,739.6667
If the quotient is a whole number, then 3 and 35,818,739.6667 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 | 107,456,219 | |
| -1 | -107,456,219 |
Let's try dividing by 4:
107,456,219 ÷ 4 = 26,864,054.75
If the quotient is a whole number, then 4 and 26,864,054.75 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 | 107,456,219 | |
| -1 | 107,456,219 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 199 | 569 | 949 | 2,587 | 7,397 | 14,527 | 41,537 | 113,231 | 188,851 | 539,981 | 1,472,003 | 8,265,863 | 107,456,219 |
| -1 | -13 | -73 | -199 | -569 | -949 | -2,587 | -7,397 | -14,527 | -41,537 | -113,231 | -188,851 | -539,981 | -1,472,003 | -8,265,863 | -107,456,219 |
