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 360,412,919, 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 | 360,412,919 | |
| -1 | -360,412,919 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 360,412,919.
Example:
1 x 360,412,919 = 360,412,919
and
-1 x -360,412,919 = 360,412,919
Notice both answers equal 360,412,919
With that explanation out of the way, let's continue. Next, we take the number 360,412,919 and divide it by 2:
360,412,919 ÷ 2 = 180,206,459.5
If the quotient is a whole number, then 2 and 180,206,459.5 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 | 360,412,919 | |
| -1 | -360,412,919 |
Now, we try dividing 360,412,919 by 3:
360,412,919 ÷ 3 = 120,137,639.6667
If the quotient is a whole number, then 3 and 120,137,639.6667 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 | 360,412,919 | |
| -1 | -360,412,919 |
Let's try dividing by 4:
360,412,919 ÷ 4 = 90,103,229.75
If the quotient is a whole number, then 4 and 90,103,229.75 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 | 360,412,919 | |
| -1 | 360,412,919 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 127 | 779 | 2,413 | 3,643 | 5,207 | 69,217 | 98,933 | 149,363 | 462,661 | 2,837,897 | 8,790,559 | 18,969,101 | 360,412,919 |
| -1 | -19 | -41 | -127 | -779 | -2,413 | -3,643 | -5,207 | -69,217 | -98,933 | -149,363 | -462,661 | -2,837,897 | -8,790,559 | -18,969,101 | -360,412,919 |
