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 210,453,233, 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 | 210,453,233 | |
| -1 | -210,453,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 210,453,233.
Example:
1 x 210,453,233 = 210,453,233
and
-1 x -210,453,233 = 210,453,233
Notice both answers equal 210,453,233
With that explanation out of the way, let's continue. Next, we take the number 210,453,233 and divide it by 2:
210,453,233 ÷ 2 = 105,226,616.5
If the quotient is a whole number, then 2 and 105,226,616.5 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 | 210,453,233 | |
| -1 | -210,453,233 |
Now, we try dividing 210,453,233 by 3:
210,453,233 ÷ 3 = 70,151,077.6667
If the quotient is a whole number, then 3 and 70,151,077.6667 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 | 210,453,233 | |
| -1 | -210,453,233 |
Let's try dividing by 4:
210,453,233 ÷ 4 = 52,613,308.25
If the quotient is a whole number, then 4 and 52,613,308.25 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 | 210,453,233 | |
| -1 | 210,453,233 |
If you did it right, you will end up with this table:
| 1 | 61 | 73 | 167 | 283 | 4,453 | 10,187 | 12,191 | 17,263 | 20,659 | 47,261 | 743,651 | 1,260,199 | 2,882,921 | 3,450,053 | 210,453,233 |
| -1 | -61 | -73 | -167 | -283 | -4,453 | -10,187 | -12,191 | -17,263 | -20,659 | -47,261 | -743,651 | -1,260,199 | -2,882,921 | -3,450,053 | -210,453,233 |
