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 176,660,267, 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 | 176,660,267 | |
| -1 | -176,660,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,660,267.
Example:
1 x 176,660,267 = 176,660,267
and
-1 x -176,660,267 = 176,660,267
Notice both answers equal 176,660,267
With that explanation out of the way, let's continue. Next, we take the number 176,660,267 and divide it by 2:
176,660,267 ÷ 2 = 88,330,133.5
If the quotient is a whole number, then 2 and 88,330,133.5 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 | 176,660,267 | |
| -1 | -176,660,267 |
Now, we try dividing 176,660,267 by 3:
176,660,267 ÷ 3 = 58,886,755.6667
If the quotient is a whole number, then 3 and 58,886,755.6667 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 | 176,660,267 | |
| -1 | -176,660,267 |
Let's try dividing by 4:
176,660,267 ÷ 4 = 44,165,066.75
If the quotient is a whole number, then 4 and 44,165,066.75 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 | 176,660,267 | |
| -1 | 176,660,267 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 137 | 287 | 959 | 4,493 | 5,617 | 31,451 | 39,319 | 184,213 | 615,541 | 1,289,491 | 4,308,787 | 25,237,181 | 176,660,267 |
| -1 | -7 | -41 | -137 | -287 | -959 | -4,493 | -5,617 | -31,451 | -39,319 | -184,213 | -615,541 | -1,289,491 | -4,308,787 | -25,237,181 | -176,660,267 |
