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 151,434,413, 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 | 151,434,413 | |
| -1 | -151,434,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,434,413.
Example:
1 x 151,434,413 = 151,434,413
and
-1 x -151,434,413 = 151,434,413
Notice both answers equal 151,434,413
With that explanation out of the way, let's continue. Next, we take the number 151,434,413 and divide it by 2:
151,434,413 ÷ 2 = 75,717,206.5
If the quotient is a whole number, then 2 and 75,717,206.5 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 | 151,434,413 | |
| -1 | -151,434,413 |
Now, we try dividing 151,434,413 by 3:
151,434,413 ÷ 3 = 50,478,137.6667
If the quotient is a whole number, then 3 and 50,478,137.6667 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 | 151,434,413 | |
| -1 | -151,434,413 |
Let's try dividing by 4:
151,434,413 ÷ 4 = 37,858,603.25
If the quotient is a whole number, then 4 and 37,858,603.25 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 | 151,434,413 | |
| -1 | 151,434,413 |
If you did it right, you will end up with this table:
| 1 | 13 | 83 | 293 | 479 | 1,079 | 3,809 | 6,227 | 24,319 | 39,757 | 140,347 | 316,147 | 516,841 | 1,824,511 | 11,648,801 | 151,434,413 |
| -1 | -13 | -83 | -293 | -479 | -1,079 | -3,809 | -6,227 | -24,319 | -39,757 | -140,347 | -316,147 | -516,841 | -1,824,511 | -11,648,801 | -151,434,413 |
