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 236,453,555, 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 | 236,453,555 | |
| -1 | -236,453,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 236,453,555.
Example:
1 x 236,453,555 = 236,453,555
and
-1 x -236,453,555 = 236,453,555
Notice both answers equal 236,453,555
With that explanation out of the way, let's continue. Next, we take the number 236,453,555 and divide it by 2:
236,453,555 ÷ 2 = 118,226,777.5
If the quotient is a whole number, then 2 and 118,226,777.5 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 | 236,453,555 | |
| -1 | -236,453,555 |
Now, we try dividing 236,453,555 by 3:
236,453,555 ÷ 3 = 78,817,851.6667
If the quotient is a whole number, then 3 and 78,817,851.6667 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 | 236,453,555 | |
| -1 | -236,453,555 |
Let's try dividing by 4:
236,453,555 ÷ 4 = 59,113,388.75
If the quotient is a whole number, then 4 and 59,113,388.75 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 | 236,453,555 | |
| -1 | 236,453,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 359 | 1,795 | 4,667 | 10,133 | 23,335 | 50,665 | 131,729 | 658,645 | 3,637,747 | 18,188,735 | 47,290,711 | 236,453,555 |
| -1 | -5 | -13 | -65 | -359 | -1,795 | -4,667 | -10,133 | -23,335 | -50,665 | -131,729 | -658,645 | -3,637,747 | -18,188,735 | -47,290,711 | -236,453,555 |
