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 176,471,069, 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 | 176,471,069 | |
| -1 | -176,471,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,471,069.
Example:
1 x 176,471,069 = 176,471,069
and
-1 x -176,471,069 = 176,471,069
Notice both answers equal 176,471,069
With that explanation out of the way, let's continue. Next, we take the number 176,471,069 and divide it by 2:
176,471,069 ÷ 2 = 88,235,534.5
If the quotient is a whole number, then 2 and 88,235,534.5 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 | 176,471,069 | |
| -1 | -176,471,069 |
Now, we try dividing 176,471,069 by 3:
176,471,069 ÷ 3 = 58,823,689.6667
If the quotient is a whole number, then 3 and 58,823,689.6667 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 | 176,471,069 | |
| -1 | -176,471,069 |
Let's try dividing by 4:
176,471,069 ÷ 4 = 44,117,767.25
If the quotient is a whole number, then 4 and 44,117,767.25 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 | 176,471,069 | |
| -1 | 176,471,069 |
If you did it right, you will end up with this table:
| 1 | 19 | 79 | 89 | 1,321 | 1,501 | 1,691 | 7,031 | 25,099 | 104,359 | 117,569 | 133,589 | 1,982,821 | 2,233,811 | 9,287,951 | 176,471,069 |
| -1 | -19 | -79 | -89 | -1,321 | -1,501 | -1,691 | -7,031 | -25,099 | -104,359 | -117,569 | -133,589 | -1,982,821 | -2,233,811 | -9,287,951 | -176,471,069 |
