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 156,134,465, 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 | 156,134,465 | |
| -1 | -156,134,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,134,465.
Example:
1 x 156,134,465 = 156,134,465
and
-1 x -156,134,465 = 156,134,465
Notice both answers equal 156,134,465
With that explanation out of the way, let's continue. Next, we take the number 156,134,465 and divide it by 2:
156,134,465 ÷ 2 = 78,067,232.5
If the quotient is a whole number, then 2 and 78,067,232.5 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 | 156,134,465 | |
| -1 | -156,134,465 |
Now, we try dividing 156,134,465 by 3:
156,134,465 ÷ 3 = 52,044,821.6667
If the quotient is a whole number, then 3 and 52,044,821.6667 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 | 156,134,465 | |
| -1 | -156,134,465 |
Let's try dividing by 4:
156,134,465 ÷ 4 = 39,033,616.25
If the quotient is a whole number, then 4 and 39,033,616.25 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 | 156,134,465 | |
| -1 | 156,134,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 233 | 1,165 | 5,359 | 5,827 | 26,795 | 29,135 | 134,021 | 670,105 | 1,357,691 | 6,788,455 | 31,226,893 | 156,134,465 |
| -1 | -5 | -23 | -115 | -233 | -1,165 | -5,359 | -5,827 | -26,795 | -29,135 | -134,021 | -670,105 | -1,357,691 | -6,788,455 | -31,226,893 | -156,134,465 |
