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 178,080,053, 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 | 178,080,053 | |
| -1 | -178,080,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 178,080,053.
Example:
1 x 178,080,053 = 178,080,053
and
-1 x -178,080,053 = 178,080,053
Notice both answers equal 178,080,053
With that explanation out of the way, let's continue. Next, we take the number 178,080,053 and divide it by 2:
178,080,053 ÷ 2 = 89,040,026.5
If the quotient is a whole number, then 2 and 89,040,026.5 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 | 178,080,053 | |
| -1 | -178,080,053 |
Now, we try dividing 178,080,053 by 3:
178,080,053 ÷ 3 = 59,360,017.6667
If the quotient is a whole number, then 3 and 59,360,017.6667 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 | 178,080,053 | |
| -1 | -178,080,053 |
Let's try dividing by 4:
178,080,053 ÷ 4 = 44,520,013.25
If the quotient is a whole number, then 4 and 44,520,013.25 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 | 178,080,053 | |
| -1 | 178,080,053 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 347 | 421 | 1,219 | 7,981 | 9,683 | 18,391 | 22,313 | 146,087 | 422,993 | 513,199 | 3,360,001 | 7,742,611 | 178,080,053 |
| -1 | -23 | -53 | -347 | -421 | -1,219 | -7,981 | -9,683 | -18,391 | -22,313 | -146,087 | -422,993 | -513,199 | -3,360,001 | -7,742,611 | -178,080,053 |
