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 157,608,425, 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 | 157,608,425 | |
| -1 | -157,608,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 157,608,425.
Example:
1 x 157,608,425 = 157,608,425
and
-1 x -157,608,425 = 157,608,425
Notice both answers equal 157,608,425
With that explanation out of the way, let's continue. Next, we take the number 157,608,425 and divide it by 2:
157,608,425 ÷ 2 = 78,804,212.5
If the quotient is a whole number, then 2 and 78,804,212.5 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 | 157,608,425 | |
| -1 | -157,608,425 |
Now, we try dividing 157,608,425 by 3:
157,608,425 ÷ 3 = 52,536,141.6667
If the quotient is a whole number, then 3 and 52,536,141.6667 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 | 157,608,425 | |
| -1 | -157,608,425 |
Let's try dividing by 4:
157,608,425 ÷ 4 = 39,402,106.25
If the quotient is a whole number, then 4 and 39,402,106.25 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 | 157,608,425 | |
| -1 | 157,608,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 191 | 325 | 955 | 2,483 | 2,539 | 4,775 | 12,415 | 12,695 | 33,007 | 62,075 | 63,475 | 165,035 | 484,949 | 825,175 | 2,424,745 | 6,304,337 | 12,123,725 | 31,521,685 | 157,608,425 |
| -1 | -5 | -13 | -25 | -65 | -191 | -325 | -955 | -2,483 | -2,539 | -4,775 | -12,415 | -12,695 | -33,007 | -62,075 | -63,475 | -165,035 | -484,949 | -825,175 | -2,424,745 | -6,304,337 | -12,123,725 | -31,521,685 | -157,608,425 |
