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 235,156,597, 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 | 235,156,597 | |
| -1 | -235,156,597 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,156,597.
Example:
1 x 235,156,597 = 235,156,597
and
-1 x -235,156,597 = 235,156,597
Notice both answers equal 235,156,597
With that explanation out of the way, let's continue. Next, we take the number 235,156,597 and divide it by 2:
235,156,597 ÷ 2 = 117,578,298.5
If the quotient is a whole number, then 2 and 117,578,298.5 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 | 235,156,597 | |
| -1 | -235,156,597 |
Now, we try dividing 235,156,597 by 3:
235,156,597 ÷ 3 = 78,385,532.3333
If the quotient is a whole number, then 3 and 78,385,532.3333 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 | 235,156,597 | |
| -1 | -235,156,597 |
Let's try dividing by 4:
235,156,597 ÷ 4 = 58,789,149.25
If the quotient is a whole number, then 4 and 58,789,149.25 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 | 235,156,597 | |
| -1 | 235,156,597 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 19 | 221 | 247 | 323 | 4,199 | 56,003 | 728,039 | 952,051 | 1,064,057 | 12,376,663 | 13,832,741 | 18,088,969 | 235,156,597 |
| -1 | -13 | -17 | -19 | -221 | -247 | -323 | -4,199 | -56,003 | -728,039 | -952,051 | -1,064,057 | -12,376,663 | -13,832,741 | -18,088,969 | -235,156,597 |
