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 156,716,015, 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 | 156,716,015 | |
| -1 | -156,716,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,716,015.
Example:
1 x 156,716,015 = 156,716,015
and
-1 x -156,716,015 = 156,716,015
Notice both answers equal 156,716,015
With that explanation out of the way, let's continue. Next, we take the number 156,716,015 and divide it by 2:
156,716,015 ÷ 2 = 78,358,007.5
If the quotient is a whole number, then 2 and 78,358,007.5 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 | 156,716,015 | |
| -1 | -156,716,015 |
Now, we try dividing 156,716,015 by 3:
156,716,015 ÷ 3 = 52,238,671.6667
If the quotient is a whole number, then 3 and 52,238,671.6667 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 | 156,716,015 | |
| -1 | -156,716,015 |
Let's try dividing by 4:
156,716,015 ÷ 4 = 39,179,003.75
If the quotient is a whole number, then 4 and 39,179,003.75 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 | 156,716,015 | |
| -1 | 156,716,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 67 | 305 | 335 | 4,087 | 7,669 | 20,435 | 38,345 | 467,809 | 513,823 | 2,339,045 | 2,569,115 | 31,343,203 | 156,716,015 |
| -1 | -5 | -61 | -67 | -305 | -335 | -4,087 | -7,669 | -20,435 | -38,345 | -467,809 | -513,823 | -2,339,045 | -2,569,115 | -31,343,203 | -156,716,015 |
