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 154,623,703, 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 | 154,623,703 | |
| -1 | -154,623,703 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,623,703.
Example:
1 x 154,623,703 = 154,623,703
and
-1 x -154,623,703 = 154,623,703
Notice both answers equal 154,623,703
With that explanation out of the way, let's continue. Next, we take the number 154,623,703 and divide it by 2:
154,623,703 ÷ 2 = 77,311,851.5
If the quotient is a whole number, then 2 and 77,311,851.5 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 | 154,623,703 | |
| -1 | -154,623,703 |
Now, we try dividing 154,623,703 by 3:
154,623,703 ÷ 3 = 51,541,234.3333
If the quotient is a whole number, then 3 and 51,541,234.3333 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 | 154,623,703 | |
| -1 | -154,623,703 |
Let's try dividing by 4:
154,623,703 ÷ 4 = 38,655,925.75
If the quotient is a whole number, then 4 and 38,655,925.75 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 | 154,623,703 | |
| -1 | 154,623,703 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 103 | 481 | 1,339 | 3,121 | 3,811 | 40,573 | 49,543 | 115,477 | 321,463 | 1,501,201 | 4,179,019 | 11,894,131 | 154,623,703 |
| -1 | -13 | -37 | -103 | -481 | -1,339 | -3,121 | -3,811 | -40,573 | -49,543 | -115,477 | -321,463 | -1,501,201 | -4,179,019 | -11,894,131 | -154,623,703 |
