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 160,031,305, 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 | 160,031,305 | |
| -1 | -160,031,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,031,305.
Example:
1 x 160,031,305 = 160,031,305
and
-1 x -160,031,305 = 160,031,305
Notice both answers equal 160,031,305
With that explanation out of the way, let's continue. Next, we take the number 160,031,305 and divide it by 2:
160,031,305 ÷ 2 = 80,015,652.5
If the quotient is a whole number, then 2 and 80,015,652.5 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 | 160,031,305 | |
| -1 | -160,031,305 |
Now, we try dividing 160,031,305 by 3:
160,031,305 ÷ 3 = 53,343,768.3333
If the quotient is a whole number, then 3 and 53,343,768.3333 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 | 160,031,305 | |
| -1 | -160,031,305 |
Let's try dividing by 4:
160,031,305 ÷ 4 = 40,007,826.25
If the quotient is a whole number, then 4 and 40,007,826.25 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 | 160,031,305 | |
| -1 | 160,031,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 59 | 245 | 295 | 413 | 2,065 | 2,891 | 11,071 | 14,455 | 55,355 | 77,497 | 387,485 | 542,479 | 653,189 | 2,712,395 | 3,265,945 | 4,572,323 | 22,861,615 | 32,006,261 | 160,031,305 |
| -1 | -5 | -7 | -35 | -49 | -59 | -245 | -295 | -413 | -2,065 | -2,891 | -11,071 | -14,455 | -55,355 | -77,497 | -387,485 | -542,479 | -653,189 | -2,712,395 | -3,265,945 | -4,572,323 | -22,861,615 | -32,006,261 | -160,031,305 |
