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 154,566,115, 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 | 154,566,115 | |
| -1 | -154,566,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,566,115.
Example:
1 x 154,566,115 = 154,566,115
and
-1 x -154,566,115 = 154,566,115
Notice both answers equal 154,566,115
With that explanation out of the way, let's continue. Next, we take the number 154,566,115 and divide it by 2:
154,566,115 ÷ 2 = 77,283,057.5
If the quotient is a whole number, then 2 and 77,283,057.5 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 | 154,566,115 | |
| -1 | -154,566,115 |
Now, we try dividing 154,566,115 by 3:
154,566,115 ÷ 3 = 51,522,038.3333
If the quotient is a whole number, then 3 and 51,522,038.3333 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 | 154,566,115 | |
| -1 | -154,566,115 |
Let's try dividing by 4:
154,566,115 ÷ 4 = 38,641,528.75
If the quotient is a whole number, then 4 and 38,641,528.75 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 | 154,566,115 | |
| -1 | 154,566,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 479 | 2,395 | 5,269 | 5,867 | 26,345 | 29,335 | 64,537 | 322,685 | 2,810,293 | 14,051,465 | 30,913,223 | 154,566,115 |
| -1 | -5 | -11 | -55 | -479 | -2,395 | -5,269 | -5,867 | -26,345 | -29,335 | -64,537 | -322,685 | -2,810,293 | -14,051,465 | -30,913,223 | -154,566,115 |
