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 160,262,555, 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 | 160,262,555 | |
| -1 | -160,262,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,262,555.
Example:
1 x 160,262,555 = 160,262,555
and
-1 x -160,262,555 = 160,262,555
Notice both answers equal 160,262,555
With that explanation out of the way, let's continue. Next, we take the number 160,262,555 and divide it by 2:
160,262,555 ÷ 2 = 80,131,277.5
If the quotient is a whole number, then 2 and 80,131,277.5 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 | 160,262,555 | |
| -1 | -160,262,555 |
Now, we try dividing 160,262,555 by 3:
160,262,555 ÷ 3 = 53,420,851.6667
If the quotient is a whole number, then 3 and 53,420,851.6667 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 | 160,262,555 | |
| -1 | -160,262,555 |
Let's try dividing by 4:
160,262,555 ÷ 4 = 40,065,638.75
If the quotient is a whole number, then 4 and 40,065,638.75 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 | 160,262,555 | |
| -1 | 160,262,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 61 | 145 | 305 | 1,769 | 8,845 | 18,119 | 90,595 | 525,451 | 1,105,259 | 2,627,255 | 5,526,295 | 32,052,511 | 160,262,555 |
| -1 | -5 | -29 | -61 | -145 | -305 | -1,769 | -8,845 | -18,119 | -90,595 | -525,451 | -1,105,259 | -2,627,255 | -5,526,295 | -32,052,511 | -160,262,555 |
