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 162,710,233, 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 | 162,710,233 | |
| -1 | -162,710,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,710,233.
Example:
1 x 162,710,233 = 162,710,233
and
-1 x -162,710,233 = 162,710,233
Notice both answers equal 162,710,233
With that explanation out of the way, let's continue. Next, we take the number 162,710,233 and divide it by 2:
162,710,233 ÷ 2 = 81,355,116.5
If the quotient is a whole number, then 2 and 81,355,116.5 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 | 162,710,233 | |
| -1 | -162,710,233 |
Now, we try dividing 162,710,233 by 3:
162,710,233 ÷ 3 = 54,236,744.3333
If the quotient is a whole number, then 3 and 54,236,744.3333 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 | 162,710,233 | |
| -1 | -162,710,233 |
Let's try dividing by 4:
162,710,233 ÷ 4 = 40,677,558.25
If the quotient is a whole number, then 4 and 40,677,558.25 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 | 162,710,233 | |
| -1 | 162,710,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 103 | 313 | 721 | 2,191 | 5,047 | 10,609 | 15,337 | 32,239 | 74,263 | 225,673 | 519,841 | 1,579,711 | 3,320,617 | 23,244,319 | 162,710,233 |
| -1 | -7 | -49 | -103 | -313 | -721 | -2,191 | -5,047 | -10,609 | -15,337 | -32,239 | -74,263 | -225,673 | -519,841 | -1,579,711 | -3,320,617 | -23,244,319 | -162,710,233 |
