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 151,012,411, 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 | 151,012,411 | |
| -1 | -151,012,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,012,411.
Example:
1 x 151,012,411 = 151,012,411
and
-1 x -151,012,411 = 151,012,411
Notice both answers equal 151,012,411
With that explanation out of the way, let's continue. Next, we take the number 151,012,411 and divide it by 2:
151,012,411 ÷ 2 = 75,506,205.5
If the quotient is a whole number, then 2 and 75,506,205.5 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 | 151,012,411 | |
| -1 | -151,012,411 |
Now, we try dividing 151,012,411 by 3:
151,012,411 ÷ 3 = 50,337,470.3333
If the quotient is a whole number, then 3 and 50,337,470.3333 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 | 151,012,411 | |
| -1 | -151,012,411 |
Let's try dividing by 4:
151,012,411 ÷ 4 = 37,753,102.75
If the quotient is a whole number, then 4 and 37,753,102.75 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 | 151,012,411 | |
| -1 | 151,012,411 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 23 | 187 | 253 | 391 | 4,301 | 35,111 | 386,221 | 596,887 | 807,553 | 6,565,757 | 8,883,083 | 13,728,401 | 151,012,411 |
| -1 | -11 | -17 | -23 | -187 | -253 | -391 | -4,301 | -35,111 | -386,221 | -596,887 | -807,553 | -6,565,757 | -8,883,083 | -13,728,401 | -151,012,411 |
