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 156,775,115, 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 | 156,775,115 | |
| -1 | -156,775,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,775,115.
Example:
1 x 156,775,115 = 156,775,115
and
-1 x -156,775,115 = 156,775,115
Notice both answers equal 156,775,115
With that explanation out of the way, let's continue. Next, we take the number 156,775,115 and divide it by 2:
156,775,115 ÷ 2 = 78,387,557.5
If the quotient is a whole number, then 2 and 78,387,557.5 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 | 156,775,115 | |
| -1 | -156,775,115 |
Now, we try dividing 156,775,115 by 3:
156,775,115 ÷ 3 = 52,258,371.6667
If the quotient is a whole number, then 3 and 52,258,371.6667 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 | 156,775,115 | |
| -1 | -156,775,115 |
Let's try dividing by 4:
156,775,115 ÷ 4 = 39,193,778.75
If the quotient is a whole number, then 4 and 39,193,778.75 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 | 156,775,115 | |
| -1 | 156,775,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,709 | 2,621 | 8,545 | 11,963 | 13,105 | 18,347 | 59,815 | 91,735 | 4,479,289 | 22,396,445 | 31,355,023 | 156,775,115 |
| -1 | -5 | -7 | -35 | -1,709 | -2,621 | -8,545 | -11,963 | -13,105 | -18,347 | -59,815 | -91,735 | -4,479,289 | -22,396,445 | -31,355,023 | -156,775,115 |
