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 236,254,151, 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 | 236,254,151 | |
| -1 | -236,254,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 236,254,151.
Example:
1 x 236,254,151 = 236,254,151
and
-1 x -236,254,151 = 236,254,151
Notice both answers equal 236,254,151
With that explanation out of the way, let's continue. Next, we take the number 236,254,151 and divide it by 2:
236,254,151 ÷ 2 = 118,127,075.5
If the quotient is a whole number, then 2 and 118,127,075.5 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 | 236,254,151 | |
| -1 | -236,254,151 |
Now, we try dividing 236,254,151 by 3:
236,254,151 ÷ 3 = 78,751,383.6667
If the quotient is a whole number, then 3 and 78,751,383.6667 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 | 236,254,151 | |
| -1 | -236,254,151 |
Let's try dividing by 4:
236,254,151 ÷ 4 = 59,063,537.75
If the quotient is a whole number, then 4 and 59,063,537.75 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 | 236,254,151 | |
| -1 | 236,254,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 104,491 | 731,437 | 1,776,347 | 1,985,329 | 12,434,429 | 13,897,303 | 33,750,593 | 236,254,151 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -104,491 | -731,437 | -1,776,347 | -1,985,329 | -12,434,429 | -13,897,303 | -33,750,593 | -236,254,151 |
