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 109,578,667, 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 | 109,578,667 | |
| -1 | -109,578,667 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 109,578,667.
Example:
1 x 109,578,667 = 109,578,667
and
-1 x -109,578,667 = 109,578,667
Notice both answers equal 109,578,667
With that explanation out of the way, let's continue. Next, we take the number 109,578,667 and divide it by 2:
109,578,667 ÷ 2 = 54,789,333.5
If the quotient is a whole number, then 2 and 54,789,333.5 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 | 109,578,667 | |
| -1 | -109,578,667 |
Now, we try dividing 109,578,667 by 3:
109,578,667 ÷ 3 = 36,526,222.3333
If the quotient is a whole number, then 3 and 36,526,222.3333 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 | 109,578,667 | |
| -1 | -109,578,667 |
Let's try dividing by 4:
109,578,667 ÷ 4 = 27,394,666.75
If the quotient is a whole number, then 4 and 27,394,666.75 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 | 109,578,667 | |
| -1 | 109,578,667 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 181 | 517 | 1,171 | 1,991 | 8,507 | 12,881 | 55,037 | 93,577 | 211,951 | 605,407 | 2,331,461 | 9,961,697 | 109,578,667 |
| -1 | -11 | -47 | -181 | -517 | -1,171 | -1,991 | -8,507 | -12,881 | -55,037 | -93,577 | -211,951 | -605,407 | -2,331,461 | -9,961,697 | -109,578,667 |
