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 179,426,045, 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 | 179,426,045 | |
| -1 | -179,426,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 179,426,045.
Example:
1 x 179,426,045 = 179,426,045
and
-1 x -179,426,045 = 179,426,045
Notice both answers equal 179,426,045
With that explanation out of the way, let's continue. Next, we take the number 179,426,045 and divide it by 2:
179,426,045 ÷ 2 = 89,713,022.5
If the quotient is a whole number, then 2 and 89,713,022.5 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 | 179,426,045 | |
| -1 | -179,426,045 |
Now, we try dividing 179,426,045 by 3:
179,426,045 ÷ 3 = 59,808,681.6667
If the quotient is a whole number, then 3 and 59,808,681.6667 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 | 179,426,045 | |
| -1 | -179,426,045 |
Let's try dividing by 4:
179,426,045 ÷ 4 = 44,856,511.25
If the quotient is a whole number, then 4 and 44,856,511.25 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 | 179,426,045 | |
| -1 | 179,426,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 41 | 145 | 205 | 1,189 | 5,945 | 30,181 | 150,905 | 875,249 | 1,237,421 | 4,376,245 | 6,187,105 | 35,885,209 | 179,426,045 |
| -1 | -5 | -29 | -41 | -145 | -205 | -1,189 | -5,945 | -30,181 | -150,905 | -875,249 | -1,237,421 | -4,376,245 | -6,187,105 | -35,885,209 | -179,426,045 |
