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 152,454,125, 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 | 152,454,125 | |
| -1 | -152,454,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,454,125.
Example:
1 x 152,454,125 = 152,454,125
and
-1 x -152,454,125 = 152,454,125
Notice both answers equal 152,454,125
With that explanation out of the way, let's continue. Next, we take the number 152,454,125 and divide it by 2:
152,454,125 ÷ 2 = 76,227,062.5
If the quotient is a whole number, then 2 and 76,227,062.5 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 | 152,454,125 | |
| -1 | -152,454,125 |
Now, we try dividing 152,454,125 by 3:
152,454,125 ÷ 3 = 50,818,041.6667
If the quotient is a whole number, then 3 and 50,818,041.6667 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 | 152,454,125 | |
| -1 | -152,454,125 |
Let's try dividing by 4:
152,454,125 ÷ 4 = 38,113,531.25
If the quotient is a whole number, then 4 and 38,113,531.25 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 | 152,454,125 | |
| -1 | 152,454,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 125 | 155 | 775 | 3,875 | 39,343 | 196,715 | 983,575 | 1,219,633 | 4,917,875 | 6,098,165 | 30,490,825 | 152,454,125 |
| -1 | -5 | -25 | -31 | -125 | -155 | -775 | -3,875 | -39,343 | -196,715 | -983,575 | -1,219,633 | -4,917,875 | -6,098,165 | -30,490,825 | -152,454,125 |
