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 151,685,747, 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 | 151,685,747 | |
| -1 | -151,685,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,685,747.
Example:
1 x 151,685,747 = 151,685,747
and
-1 x -151,685,747 = 151,685,747
Notice both answers equal 151,685,747
With that explanation out of the way, let's continue. Next, we take the number 151,685,747 and divide it by 2:
151,685,747 ÷ 2 = 75,842,873.5
If the quotient is a whole number, then 2 and 75,842,873.5 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 | 151,685,747 | |
| -1 | -151,685,747 |
Now, we try dividing 151,685,747 by 3:
151,685,747 ÷ 3 = 50,561,915.6667
If the quotient is a whole number, then 3 and 50,561,915.6667 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 | 151,685,747 | |
| -1 | -151,685,747 |
Let's try dividing by 4:
151,685,747 ÷ 4 = 37,921,436.75
If the quotient is a whole number, then 4 and 37,921,436.75 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 | 151,685,747 | |
| -1 | 151,685,747 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 313 | 493 | 983 | 5,321 | 9,077 | 16,711 | 28,507 | 154,309 | 307,679 | 484,619 | 5,230,543 | 8,922,691 | 151,685,747 |
| -1 | -17 | -29 | -313 | -493 | -983 | -5,321 | -9,077 | -16,711 | -28,507 | -154,309 | -307,679 | -484,619 | -5,230,543 | -8,922,691 | -151,685,747 |
