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 153,063,413, 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 | 153,063,413 | |
| -1 | -153,063,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,063,413.
Example:
1 x 153,063,413 = 153,063,413
and
-1 x -153,063,413 = 153,063,413
Notice both answers equal 153,063,413
With that explanation out of the way, let's continue. Next, we take the number 153,063,413 and divide it by 2:
153,063,413 ÷ 2 = 76,531,706.5
If the quotient is a whole number, then 2 and 76,531,706.5 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 | 153,063,413 | |
| -1 | -153,063,413 |
Now, we try dividing 153,063,413 by 3:
153,063,413 ÷ 3 = 51,021,137.6667
If the quotient is a whole number, then 3 and 51,021,137.6667 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 | 153,063,413 | |
| -1 | -153,063,413 |
Let's try dividing by 4:
153,063,413 ÷ 4 = 38,265,853.25
If the quotient is a whole number, then 4 and 38,265,853.25 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 | 153,063,413 | |
| -1 | 153,063,413 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 131 | 851 | 1,373 | 3,013 | 4,847 | 31,579 | 50,801 | 111,481 | 179,863 | 1,168,423 | 4,136,849 | 6,654,931 | 153,063,413 |
| -1 | -23 | -37 | -131 | -851 | -1,373 | -3,013 | -4,847 | -31,579 | -50,801 | -111,481 | -179,863 | -1,168,423 | -4,136,849 | -6,654,931 | -153,063,413 |
