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 234,142,355, 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 | 234,142,355 | |
| -1 | -234,142,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,142,355.
Example:
1 x 234,142,355 = 234,142,355
and
-1 x -234,142,355 = 234,142,355
Notice both answers equal 234,142,355
With that explanation out of the way, let's continue. Next, we take the number 234,142,355 and divide it by 2:
234,142,355 ÷ 2 = 117,071,177.5
If the quotient is a whole number, then 2 and 117,071,177.5 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 | 234,142,355 | |
| -1 | -234,142,355 |
Now, we try dividing 234,142,355 by 3:
234,142,355 ÷ 3 = 78,047,451.6667
If the quotient is a whole number, then 3 and 78,047,451.6667 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 | 234,142,355 | |
| -1 | -234,142,355 |
Let's try dividing by 4:
234,142,355 ÷ 4 = 58,535,588.75
If the quotient is a whole number, then 4 and 58,535,588.75 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 | 234,142,355 | |
| -1 | 234,142,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 109 | 349 | 545 | 1,231 | 1,745 | 6,155 | 38,041 | 134,179 | 190,205 | 429,619 | 670,895 | 2,148,095 | 46,828,471 | 234,142,355 |
| -1 | -5 | -109 | -349 | -545 | -1,231 | -1,745 | -6,155 | -38,041 | -134,179 | -190,205 | -429,619 | -670,895 | -2,148,095 | -46,828,471 | -234,142,355 |
