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 160,010,653, 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 | 160,010,653 | |
| -1 | -160,010,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,010,653.
Example:
1 x 160,010,653 = 160,010,653
and
-1 x -160,010,653 = 160,010,653
Notice both answers equal 160,010,653
With that explanation out of the way, let's continue. Next, we take the number 160,010,653 and divide it by 2:
160,010,653 ÷ 2 = 80,005,326.5
If the quotient is a whole number, then 2 and 80,005,326.5 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 | 160,010,653 | |
| -1 | -160,010,653 |
Now, we try dividing 160,010,653 by 3:
160,010,653 ÷ 3 = 53,336,884.3333
If the quotient is a whole number, then 3 and 53,336,884.3333 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 | 160,010,653 | |
| -1 | -160,010,653 |
Let's try dividing by 4:
160,010,653 ÷ 4 = 40,002,663.25
If the quotient is a whole number, then 4 and 40,002,663.25 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 | 160,010,653 | |
| -1 | 160,010,653 |
If you did it right, you will end up with this table:
| 1 | 11 | 149 | 233 | 419 | 1,639 | 2,563 | 4,609 | 34,717 | 62,431 | 97,627 | 381,887 | 686,741 | 1,073,897 | 14,546,423 | 160,010,653 |
| -1 | -11 | -149 | -233 | -419 | -1,639 | -2,563 | -4,609 | -34,717 | -62,431 | -97,627 | -381,887 | -686,741 | -1,073,897 | -14,546,423 | -160,010,653 |
