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 154,871,101, 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 | 154,871,101 | |
| -1 | -154,871,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,871,101.
Example:
1 x 154,871,101 = 154,871,101
and
-1 x -154,871,101 = 154,871,101
Notice both answers equal 154,871,101
With that explanation out of the way, let's continue. Next, we take the number 154,871,101 and divide it by 2:
154,871,101 ÷ 2 = 77,435,550.5
If the quotient is a whole number, then 2 and 77,435,550.5 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 | 154,871,101 | |
| -1 | -154,871,101 |
Now, we try dividing 154,871,101 by 3:
154,871,101 ÷ 3 = 51,623,700.3333
If the quotient is a whole number, then 3 and 51,623,700.3333 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 | 154,871,101 | |
| -1 | -154,871,101 |
Let's try dividing by 4:
154,871,101 ÷ 4 = 38,717,775.25
If the quotient is a whole number, then 4 and 38,717,775.25 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 | 154,871,101 | |
| -1 | 154,871,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 269 | 1,883 | 2,959 | 7,477 | 20,713 | 52,339 | 82,247 | 575,729 | 2,011,313 | 14,079,191 | 22,124,443 | 154,871,101 |
| -1 | -7 | -11 | -77 | -269 | -1,883 | -2,959 | -7,477 | -20,713 | -52,339 | -82,247 | -575,729 | -2,011,313 | -14,079,191 | -22,124,443 | -154,871,101 |
