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 151,011,113, 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 | 151,011,113 | |
| -1 | -151,011,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,011,113.
Example:
1 x 151,011,113 = 151,011,113
and
-1 x -151,011,113 = 151,011,113
Notice both answers equal 151,011,113
With that explanation out of the way, let's continue. Next, we take the number 151,011,113 and divide it by 2:
151,011,113 ÷ 2 = 75,505,556.5
If the quotient is a whole number, then 2 and 75,505,556.5 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 | 151,011,113 | |
| -1 | -151,011,113 |
Now, we try dividing 151,011,113 by 3:
151,011,113 ÷ 3 = 50,337,037.6667
If the quotient is a whole number, then 3 and 50,337,037.6667 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 | 151,011,113 | |
| -1 | -151,011,113 |
Let's try dividing by 4:
151,011,113 ÷ 4 = 37,752,778.25
If the quotient is a whole number, then 4 and 37,752,778.25 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 | 151,011,113 | |
| -1 | 151,011,113 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 193 | 857 | 913 | 2,123 | 9,427 | 16,019 | 71,131 | 165,401 | 176,209 | 782,441 | 1,819,411 | 13,728,283 | 151,011,113 |
| -1 | -11 | -83 | -193 | -857 | -913 | -2,123 | -9,427 | -16,019 | -71,131 | -165,401 | -176,209 | -782,441 | -1,819,411 | -13,728,283 | -151,011,113 |
