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 151,352,029, 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 | 151,352,029 | |
| -1 | -151,352,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,352,029.
Example:
1 x 151,352,029 = 151,352,029
and
-1 x -151,352,029 = 151,352,029
Notice both answers equal 151,352,029
With that explanation out of the way, let's continue. Next, we take the number 151,352,029 and divide it by 2:
151,352,029 ÷ 2 = 75,676,014.5
If the quotient is a whole number, then 2 and 75,676,014.5 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 | 151,352,029 | |
| -1 | -151,352,029 |
Now, we try dividing 151,352,029 by 3:
151,352,029 ÷ 3 = 50,450,676.3333
If the quotient is a whole number, then 3 and 50,450,676.3333 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 | 151,352,029 | |
| -1 | -151,352,029 |
Let's try dividing by 4:
151,352,029 ÷ 4 = 37,838,007.25
If the quotient is a whole number, then 4 and 37,838,007.25 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 | 151,352,029 | |
| -1 | 151,352,029 |
If you did it right, you will end up with this table:
| 1 | 23 | 131 | 191 | 263 | 3,013 | 4,393 | 6,049 | 25,021 | 34,453 | 50,233 | 575,483 | 792,419 | 1,155,359 | 6,580,523 | 151,352,029 |
| -1 | -23 | -131 | -191 | -263 | -3,013 | -4,393 | -6,049 | -25,021 | -34,453 | -50,233 | -575,483 | -792,419 | -1,155,359 | -6,580,523 | -151,352,029 |
