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 156,605,011, 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 | 156,605,011 | |
| -1 | -156,605,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,605,011.
Example:
1 x 156,605,011 = 156,605,011
and
-1 x -156,605,011 = 156,605,011
Notice both answers equal 156,605,011
With that explanation out of the way, let's continue. Next, we take the number 156,605,011 and divide it by 2:
156,605,011 ÷ 2 = 78,302,505.5
If the quotient is a whole number, then 2 and 78,302,505.5 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 | 156,605,011 | |
| -1 | -156,605,011 |
Now, we try dividing 156,605,011 by 3:
156,605,011 ÷ 3 = 52,201,670.3333
If the quotient is a whole number, then 3 and 52,201,670.3333 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 | 156,605,011 | |
| -1 | -156,605,011 |
Let's try dividing by 4:
156,605,011 ÷ 4 = 39,151,252.75
If the quotient is a whole number, then 4 and 39,151,252.75 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 | 156,605,011 | |
| -1 | 156,605,011 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 103 | 817 | 1,861 | 1,957 | 4,429 | 35,359 | 80,023 | 84,151 | 191,683 | 1,520,437 | 3,641,977 | 8,242,369 | 156,605,011 |
| -1 | -19 | -43 | -103 | -817 | -1,861 | -1,957 | -4,429 | -35,359 | -80,023 | -84,151 | -191,683 | -1,520,437 | -3,641,977 | -8,242,369 | -156,605,011 |
