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 436,742,015, 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 | 436,742,015 | |
| -1 | -436,742,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 436,742,015.
Example:
1 x 436,742,015 = 436,742,015
and
-1 x -436,742,015 = 436,742,015
Notice both answers equal 436,742,015
With that explanation out of the way, let's continue. Next, we take the number 436,742,015 and divide it by 2:
436,742,015 ÷ 2 = 218,371,007.5
If the quotient is a whole number, then 2 and 218,371,007.5 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 | 436,742,015 | |
| -1 | -436,742,015 |
Now, we try dividing 436,742,015 by 3:
436,742,015 ÷ 3 = 145,580,671.6667
If the quotient is a whole number, then 3 and 145,580,671.6667 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 | 436,742,015 | |
| -1 | -436,742,015 |
Let's try dividing by 4:
436,742,015 ÷ 4 = 109,185,503.75
If the quotient is a whole number, then 4 and 109,185,503.75 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 | 436,742,015 | |
| -1 | 436,742,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 485 | 769 | 1,171 | 3,845 | 5,855 | 74,593 | 113,587 | 372,965 | 567,935 | 900,499 | 4,502,495 | 87,348,403 | 436,742,015 |
| -1 | -5 | -97 | -485 | -769 | -1,171 | -3,845 | -5,855 | -74,593 | -113,587 | -372,965 | -567,935 | -900,499 | -4,502,495 | -87,348,403 | -436,742,015 |
