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 157,824,073, 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 | 157,824,073 | |
| -1 | -157,824,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 157,824,073.
Example:
1 x 157,824,073 = 157,824,073
and
-1 x -157,824,073 = 157,824,073
Notice both answers equal 157,824,073
With that explanation out of the way, let's continue. Next, we take the number 157,824,073 and divide it by 2:
157,824,073 ÷ 2 = 78,912,036.5
If the quotient is a whole number, then 2 and 78,912,036.5 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 | 157,824,073 | |
| -1 | -157,824,073 |
Now, we try dividing 157,824,073 by 3:
157,824,073 ÷ 3 = 52,608,024.3333
If the quotient is a whole number, then 3 and 52,608,024.3333 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 | 157,824,073 | |
| -1 | -157,824,073 |
Let's try dividing by 4:
157,824,073 ÷ 4 = 39,456,018.25
If the quotient is a whole number, then 4 and 39,456,018.25 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 | 157,824,073 | |
| -1 | 157,824,073 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 47 | 187 | 517 | 799 | 8,789 | 17,957 | 197,527 | 305,269 | 843,979 | 3,357,959 | 9,283,769 | 14,347,643 | 157,824,073 |
| -1 | -11 | -17 | -47 | -187 | -517 | -799 | -8,789 | -17,957 | -197,527 | -305,269 | -843,979 | -3,357,959 | -9,283,769 | -14,347,643 | -157,824,073 |
