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 160,014,751, 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 | 160,014,751 | |
| -1 | -160,014,751 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,014,751.
Example:
1 x 160,014,751 = 160,014,751
and
-1 x -160,014,751 = 160,014,751
Notice both answers equal 160,014,751
With that explanation out of the way, let's continue. Next, we take the number 160,014,751 and divide it by 2:
160,014,751 ÷ 2 = 80,007,375.5
If the quotient is a whole number, then 2 and 80,007,375.5 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 | 160,014,751 | |
| -1 | -160,014,751 |
Now, we try dividing 160,014,751 by 3:
160,014,751 ÷ 3 = 53,338,250.3333
If the quotient is a whole number, then 3 and 53,338,250.3333 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 | 160,014,751 | |
| -1 | -160,014,751 |
Let's try dividing by 4:
160,014,751 ÷ 4 = 40,003,687.75
If the quotient is a whole number, then 4 and 40,003,687.75 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 | 160,014,751 | |
| -1 | 160,014,751 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 37 | 247 | 481 | 703 | 9,139 | 17,509 | 227,617 | 332,671 | 647,833 | 4,324,723 | 8,421,829 | 12,308,827 | 160,014,751 |
| -1 | -13 | -19 | -37 | -247 | -481 | -703 | -9,139 | -17,509 | -227,617 | -332,671 | -647,833 | -4,324,723 | -8,421,829 | -12,308,827 | -160,014,751 |
