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 179,368,553, 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 | 179,368,553 | |
| -1 | -179,368,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 179,368,553.
Example:
1 x 179,368,553 = 179,368,553
and
-1 x -179,368,553 = 179,368,553
Notice both answers equal 179,368,553
With that explanation out of the way, let's continue. Next, we take the number 179,368,553 and divide it by 2:
179,368,553 ÷ 2 = 89,684,276.5
If the quotient is a whole number, then 2 and 89,684,276.5 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 | 179,368,553 | |
| -1 | -179,368,553 |
Now, we try dividing 179,368,553 by 3:
179,368,553 ÷ 3 = 59,789,517.6667
If the quotient is a whole number, then 3 and 59,789,517.6667 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 | 179,368,553 | |
| -1 | -179,368,553 |
Let's try dividing by 4:
179,368,553 ÷ 4 = 44,842,138.25
If the quotient is a whole number, then 4 and 44,842,138.25 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 | 179,368,553 | |
| -1 | 179,368,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 89 | 91 | 623 | 1,157 | 8,099 | 22,147 | 155,029 | 287,911 | 1,971,083 | 2,015,377 | 13,797,581 | 25,624,079 | 179,368,553 |
| -1 | -7 | -13 | -89 | -91 | -623 | -1,157 | -8,099 | -22,147 | -155,029 | -287,911 | -1,971,083 | -2,015,377 | -13,797,581 | -25,624,079 | -179,368,553 |
