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 176,660,263, 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 | 176,660,263 | |
| -1 | -176,660,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,660,263.
Example:
1 x 176,660,263 = 176,660,263
and
-1 x -176,660,263 = 176,660,263
Notice both answers equal 176,660,263
With that explanation out of the way, let's continue. Next, we take the number 176,660,263 and divide it by 2:
176,660,263 ÷ 2 = 88,330,131.5
If the quotient is a whole number, then 2 and 88,330,131.5 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 | 176,660,263 | |
| -1 | -176,660,263 |
Now, we try dividing 176,660,263 by 3:
176,660,263 ÷ 3 = 58,886,754.3333
If the quotient is a whole number, then 3 and 58,886,754.3333 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 | 176,660,263 | |
| -1 | -176,660,263 |
Let's try dividing by 4:
176,660,263 ÷ 4 = 44,165,065.75
If the quotient is a whole number, then 4 and 44,165,065.75 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 | 176,660,263 | |
| -1 | 176,660,263 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 47 | 169 | 299 | 611 | 967 | 1,081 | 3,887 | 7,943 | 12,571 | 14,053 | 22,241 | 45,449 | 163,423 | 182,689 | 289,133 | 590,837 | 1,045,327 | 3,758,729 | 7,680,881 | 13,589,251 | 176,660,263 |
| -1 | -13 | -23 | -47 | -169 | -299 | -611 | -967 | -1,081 | -3,887 | -7,943 | -12,571 | -14,053 | -22,241 | -45,449 | -163,423 | -182,689 | -289,133 | -590,837 | -1,045,327 | -3,758,729 | -7,680,881 | -13,589,251 | -176,660,263 |
