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 157,093,651, 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 | 157,093,651 | |
| -1 | -157,093,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 157,093,651.
Example:
1 x 157,093,651 = 157,093,651
and
-1 x -157,093,651 = 157,093,651
Notice both answers equal 157,093,651
With that explanation out of the way, let's continue. Next, we take the number 157,093,651 and divide it by 2:
157,093,651 ÷ 2 = 78,546,825.5
If the quotient is a whole number, then 2 and 78,546,825.5 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 | 157,093,651 | |
| -1 | -157,093,651 |
Now, we try dividing 157,093,651 by 3:
157,093,651 ÷ 3 = 52,364,550.3333
If the quotient is a whole number, then 3 and 52,364,550.3333 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 | 157,093,651 | |
| -1 | -157,093,651 |
Let's try dividing by 4:
157,093,651 ÷ 4 = 39,273,412.75
If the quotient is a whole number, then 4 and 39,273,412.75 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 | 157,093,651 | |
| -1 | 157,093,651 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 2,431 | 64,621 | 710,831 | 840,073 | 1,098,557 | 9,240,803 | 12,084,127 | 14,281,241 | 157,093,651 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -2,431 | -64,621 | -710,831 | -840,073 | -1,098,557 | -9,240,803 | -12,084,127 | -14,281,241 | -157,093,651 |
