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 157,541,695, 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 | 157,541,695 | |
| -1 | -157,541,695 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 157,541,695.
Example:
1 x 157,541,695 = 157,541,695
and
-1 x -157,541,695 = 157,541,695
Notice both answers equal 157,541,695
With that explanation out of the way, let's continue. Next, we take the number 157,541,695 and divide it by 2:
157,541,695 ÷ 2 = 78,770,847.5
If the quotient is a whole number, then 2 and 78,770,847.5 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 | 157,541,695 | |
| -1 | -157,541,695 |
Now, we try dividing 157,541,695 by 3:
157,541,695 ÷ 3 = 52,513,898.3333
If the quotient is a whole number, then 3 and 52,513,898.3333 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 | 157,541,695 | |
| -1 | -157,541,695 |
Let's try dividing by 4:
157,541,695 ÷ 4 = 39,385,423.75
If the quotient is a whole number, then 4 and 39,385,423.75 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 | 157,541,695 | |
| -1 | 157,541,695 |
If you did it right, you will end up with this table:
| 1 | 5 | 223 | 229 | 617 | 1,115 | 1,145 | 3,085 | 51,067 | 137,591 | 141,293 | 255,335 | 687,955 | 706,465 | 31,508,339 | 157,541,695 |
| -1 | -5 | -223 | -229 | -617 | -1,115 | -1,145 | -3,085 | -51,067 | -137,591 | -141,293 | -255,335 | -687,955 | -706,465 | -31,508,339 | -157,541,695 |
