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 154,662,545, 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 | 154,662,545 | |
| -1 | -154,662,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,662,545.
Example:
1 x 154,662,545 = 154,662,545
and
-1 x -154,662,545 = 154,662,545
Notice both answers equal 154,662,545
With that explanation out of the way, let's continue. Next, we take the number 154,662,545 and divide it by 2:
154,662,545 ÷ 2 = 77,331,272.5
If the quotient is a whole number, then 2 and 77,331,272.5 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 | 154,662,545 | |
| -1 | -154,662,545 |
Now, we try dividing 154,662,545 by 3:
154,662,545 ÷ 3 = 51,554,181.6667
If the quotient is a whole number, then 3 and 51,554,181.6667 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 | 154,662,545 | |
| -1 | -154,662,545 |
Let's try dividing by 4:
154,662,545 ÷ 4 = 38,665,636.25
If the quotient is a whole number, then 4 and 38,665,636.25 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 | 154,662,545 | |
| -1 | 154,662,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 365 | 491 | 863 | 2,455 | 4,315 | 35,843 | 62,999 | 179,215 | 314,995 | 423,733 | 2,118,665 | 30,932,509 | 154,662,545 |
| -1 | -5 | -73 | -365 | -491 | -863 | -2,455 | -4,315 | -35,843 | -62,999 | -179,215 | -314,995 | -423,733 | -2,118,665 | -30,932,509 | -154,662,545 |
