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 154,666,145, 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 | 154,666,145 | |
| -1 | -154,666,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,666,145.
Example:
1 x 154,666,145 = 154,666,145
and
-1 x -154,666,145 = 154,666,145
Notice both answers equal 154,666,145
With that explanation out of the way, let's continue. Next, we take the number 154,666,145 and divide it by 2:
154,666,145 ÷ 2 = 77,333,072.5
If the quotient is a whole number, then 2 and 77,333,072.5 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 | 154,666,145 | |
| -1 | -154,666,145 |
Now, we try dividing 154,666,145 by 3:
154,666,145 ÷ 3 = 51,555,381.6667
If the quotient is a whole number, then 3 and 51,555,381.6667 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 | 154,666,145 | |
| -1 | -154,666,145 |
Let's try dividing by 4:
154,666,145 ÷ 4 = 38,666,536.25
If the quotient is a whole number, then 4 and 38,666,536.25 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 | 154,666,145 | |
| -1 | 154,666,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 41 | 115 | 205 | 943 | 4,715 | 32,803 | 164,015 | 754,469 | 1,344,923 | 3,772,345 | 6,724,615 | 30,933,229 | 154,666,145 |
| -1 | -5 | -23 | -41 | -115 | -205 | -943 | -4,715 | -32,803 | -164,015 | -754,469 | -1,344,923 | -3,772,345 | -6,724,615 | -30,933,229 | -154,666,145 |
