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 156,692,485, 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 | 156,692,485 | |
| -1 | -156,692,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,692,485.
Example:
1 x 156,692,485 = 156,692,485
and
-1 x -156,692,485 = 156,692,485
Notice both answers equal 156,692,485
With that explanation out of the way, let's continue. Next, we take the number 156,692,485 and divide it by 2:
156,692,485 ÷ 2 = 78,346,242.5
If the quotient is a whole number, then 2 and 78,346,242.5 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 | 156,692,485 | |
| -1 | -156,692,485 |
Now, we try dividing 156,692,485 by 3:
156,692,485 ÷ 3 = 52,230,828.3333
If the quotient is a whole number, then 3 and 52,230,828.3333 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 | 156,692,485 | |
| -1 | -156,692,485 |
Let's try dividing by 4:
156,692,485 ÷ 4 = 39,173,121.25
If the quotient is a whole number, then 4 and 39,173,121.25 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 | 156,692,485 | |
| -1 | 156,692,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 367 | 1,835 | 5,023 | 6,239 | 25,115 | 31,195 | 85,391 | 426,955 | 1,843,441 | 9,217,205 | 31,338,497 | 156,692,485 |
| -1 | -5 | -17 | -85 | -367 | -1,835 | -5,023 | -6,239 | -25,115 | -31,195 | -85,391 | -426,955 | -1,843,441 | -9,217,205 | -31,338,497 | -156,692,485 |
