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 160,357,583, 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 | 160,357,583 | |
| -1 | -160,357,583 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,357,583.
Example:
1 x 160,357,583 = 160,357,583
and
-1 x -160,357,583 = 160,357,583
Notice both answers equal 160,357,583
With that explanation out of the way, let's continue. Next, we take the number 160,357,583 and divide it by 2:
160,357,583 ÷ 2 = 80,178,791.5
If the quotient is a whole number, then 2 and 80,178,791.5 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 | 160,357,583 | |
| -1 | -160,357,583 |
Now, we try dividing 160,357,583 by 3:
160,357,583 ÷ 3 = 53,452,527.6667
If the quotient is a whole number, then 3 and 53,452,527.6667 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 | 160,357,583 | |
| -1 | -160,357,583 |
Let's try dividing by 4:
160,357,583 ÷ 4 = 40,089,395.75
If the quotient is a whole number, then 4 and 40,089,395.75 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 | 160,357,583 | |
| -1 | 160,357,583 |
If you did it right, you will end up with this table:
| 1 | 17 | 107 | 199 | 443 | 1,819 | 3,383 | 7,531 | 21,293 | 47,401 | 88,157 | 361,981 | 805,817 | 1,498,669 | 9,432,799 | 160,357,583 |
| -1 | -17 | -107 | -199 | -443 | -1,819 | -3,383 | -7,531 | -21,293 | -47,401 | -88,157 | -361,981 | -805,817 | -1,498,669 | -9,432,799 | -160,357,583 |
