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 154,311,575, 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 | 154,311,575 | |
| -1 | -154,311,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,311,575.
Example:
1 x 154,311,575 = 154,311,575
and
-1 x -154,311,575 = 154,311,575
Notice both answers equal 154,311,575
With that explanation out of the way, let's continue. Next, we take the number 154,311,575 and divide it by 2:
154,311,575 ÷ 2 = 77,155,787.5
If the quotient is a whole number, then 2 and 77,155,787.5 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 | 154,311,575 | |
| -1 | -154,311,575 |
Now, we try dividing 154,311,575 by 3:
154,311,575 ÷ 3 = 51,437,191.6667
If the quotient is a whole number, then 3 and 51,437,191.6667 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 | 154,311,575 | |
| -1 | -154,311,575 |
Let's try dividing by 4:
154,311,575 ÷ 4 = 38,577,893.75
If the quotient is a whole number, then 4 and 38,577,893.75 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 | 154,311,575 | |
| -1 | 154,311,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 47 | 55 | 235 | 275 | 517 | 1,175 | 2,585 | 11,939 | 12,925 | 59,695 | 131,329 | 298,475 | 561,133 | 656,645 | 2,805,665 | 3,283,225 | 6,172,463 | 14,028,325 | 30,862,315 | 154,311,575 |
| -1 | -5 | -11 | -25 | -47 | -55 | -235 | -275 | -517 | -1,175 | -2,585 | -11,939 | -12,925 | -59,695 | -131,329 | -298,475 | -561,133 | -656,645 | -2,805,665 | -3,283,225 | -6,172,463 | -14,028,325 | -30,862,315 | -154,311,575 |
