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 151,156,135, 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 | 151,156,135 | |
| -1 | -151,156,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,156,135.
Example:
1 x 151,156,135 = 151,156,135
and
-1 x -151,156,135 = 151,156,135
Notice both answers equal 151,156,135
With that explanation out of the way, let's continue. Next, we take the number 151,156,135 and divide it by 2:
151,156,135 ÷ 2 = 75,578,067.5
If the quotient is a whole number, then 2 and 75,578,067.5 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 | 151,156,135 | |
| -1 | -151,156,135 |
Now, we try dividing 151,156,135 by 3:
151,156,135 ÷ 3 = 50,385,378.3333
If the quotient is a whole number, then 3 and 50,385,378.3333 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 | 151,156,135 | |
| -1 | -151,156,135 |
Let's try dividing by 4:
151,156,135 ÷ 4 = 37,789,033.75
If the quotient is a whole number, then 4 and 37,789,033.75 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 | 151,156,135 | |
| -1 | 151,156,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 41 | 65 | 169 | 205 | 533 | 845 | 2,665 | 4,363 | 6,929 | 21,815 | 34,645 | 56,719 | 178,883 | 283,595 | 737,347 | 894,415 | 2,325,479 | 3,686,735 | 11,627,395 | 30,231,227 | 151,156,135 |
| -1 | -5 | -13 | -41 | -65 | -169 | -205 | -533 | -845 | -2,665 | -4,363 | -6,929 | -21,815 | -34,645 | -56,719 | -178,883 | -283,595 | -737,347 | -894,415 | -2,325,479 | -3,686,735 | -11,627,395 | -30,231,227 | -151,156,135 |
