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 179,418,463, 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 | 179,418,463 | |
| -1 | -179,418,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 179,418,463.
Example:
1 x 179,418,463 = 179,418,463
and
-1 x -179,418,463 = 179,418,463
Notice both answers equal 179,418,463
With that explanation out of the way, let's continue. Next, we take the number 179,418,463 and divide it by 2:
179,418,463 ÷ 2 = 89,709,231.5
If the quotient is a whole number, then 2 and 89,709,231.5 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 | 179,418,463 | |
| -1 | -179,418,463 |
Now, we try dividing 179,418,463 by 3:
179,418,463 ÷ 3 = 59,806,154.3333
If the quotient is a whole number, then 3 and 59,806,154.3333 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 | 179,418,463 | |
| -1 | -179,418,463 |
Let's try dividing by 4:
179,418,463 ÷ 4 = 44,854,615.75
If the quotient is a whole number, then 4 and 44,854,615.75 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 | 179,418,463 | |
| -1 | 179,418,463 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 337 | 2,359 | 4,003 | 6,403 | 28,021 | 44,821 | 76,057 | 532,399 | 1,349,011 | 9,443,077 | 25,631,209 | 179,418,463 |
| -1 | -7 | -19 | -133 | -337 | -2,359 | -4,003 | -6,403 | -28,021 | -44,821 | -76,057 | -532,399 | -1,349,011 | -9,443,077 | -25,631,209 | -179,418,463 |
