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 153,025,411, 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 | 153,025,411 | |
| -1 | -153,025,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,025,411.
Example:
1 x 153,025,411 = 153,025,411
and
-1 x -153,025,411 = 153,025,411
Notice both answers equal 153,025,411
With that explanation out of the way, let's continue. Next, we take the number 153,025,411 and divide it by 2:
153,025,411 ÷ 2 = 76,512,705.5
If the quotient is a whole number, then 2 and 76,512,705.5 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 | 153,025,411 | |
| -1 | -153,025,411 |
Now, we try dividing 153,025,411 by 3:
153,025,411 ÷ 3 = 51,008,470.3333
If the quotient is a whole number, then 3 and 51,008,470.3333 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 | 153,025,411 | |
| -1 | -153,025,411 |
Let's try dividing by 4:
153,025,411 ÷ 4 = 38,256,352.75
If the quotient is a whole number, then 4 and 38,256,352.75 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 | 153,025,411 | |
| -1 | 153,025,411 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 133 | 209 | 1,463 | 104,597 | 732,179 | 1,150,567 | 1,987,343 | 8,053,969 | 13,911,401 | 21,860,773 | 153,025,411 |
| -1 | -7 | -11 | -19 | -77 | -133 | -209 | -1,463 | -104,597 | -732,179 | -1,150,567 | -1,987,343 | -8,053,969 | -13,911,401 | -21,860,773 | -153,025,411 |
