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 156,551,113, 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 | 156,551,113 | |
| -1 | -156,551,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,551,113.
Example:
1 x 156,551,113 = 156,551,113
and
-1 x -156,551,113 = 156,551,113
Notice both answers equal 156,551,113
With that explanation out of the way, let's continue. Next, we take the number 156,551,113 and divide it by 2:
156,551,113 ÷ 2 = 78,275,556.5
If the quotient is a whole number, then 2 and 78,275,556.5 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 | 156,551,113 | |
| -1 | -156,551,113 |
Now, we try dividing 156,551,113 by 3:
156,551,113 ÷ 3 = 52,183,704.3333
If the quotient is a whole number, then 3 and 52,183,704.3333 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 | 156,551,113 | |
| -1 | -156,551,113 |
Let's try dividing by 4:
156,551,113 ÷ 4 = 39,137,778.25
If the quotient is a whole number, then 4 and 39,137,778.25 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 | 156,551,113 | |
| -1 | 156,551,113 |
If you did it right, you will end up with this table:
| 1 | 17 | 97 | 139 | 683 | 1,649 | 2,363 | 11,611 | 13,483 | 66,251 | 94,937 | 229,211 | 1,126,267 | 1,613,929 | 9,208,889 | 156,551,113 |
| -1 | -17 | -97 | -139 | -683 | -1,649 | -2,363 | -11,611 | -13,483 | -66,251 | -94,937 | -229,211 | -1,126,267 | -1,613,929 | -9,208,889 | -156,551,113 |
