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 176,242,045, 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 | 176,242,045 | |
| -1 | -176,242,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,242,045.
Example:
1 x 176,242,045 = 176,242,045
and
-1 x -176,242,045 = 176,242,045
Notice both answers equal 176,242,045
With that explanation out of the way, let's continue. Next, we take the number 176,242,045 and divide it by 2:
176,242,045 ÷ 2 = 88,121,022.5
If the quotient is a whole number, then 2 and 88,121,022.5 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 | 176,242,045 | |
| -1 | -176,242,045 |
Now, we try dividing 176,242,045 by 3:
176,242,045 ÷ 3 = 58,747,348.3333
If the quotient is a whole number, then 3 and 58,747,348.3333 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 | 176,242,045 | |
| -1 | -176,242,045 |
Let's try dividing by 4:
176,242,045 ÷ 4 = 44,060,511.25
If the quotient is a whole number, then 4 and 44,060,511.25 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 | 176,242,045 | |
| -1 | 176,242,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,237 | 2,251 | 11,185 | 11,255 | 15,659 | 15,757 | 78,295 | 78,785 | 5,035,487 | 25,177,435 | 35,248,409 | 176,242,045 |
| -1 | -5 | -7 | -35 | -2,237 | -2,251 | -11,185 | -11,255 | -15,659 | -15,757 | -78,295 | -78,785 | -5,035,487 | -25,177,435 | -35,248,409 | -176,242,045 |
