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 40,471,151, 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 | 40,471,151 | |
| -1 | -40,471,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,471,151.
Example:
1 x 40,471,151 = 40,471,151
and
-1 x -40,471,151 = 40,471,151
Notice both answers equal 40,471,151
With that explanation out of the way, let's continue. Next, we take the number 40,471,151 and divide it by 2:
40,471,151 ÷ 2 = 20,235,575.5
If the quotient is a whole number, then 2 and 20,235,575.5 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 | 40,471,151 | |
| -1 | -40,471,151 |
Now, we try dividing 40,471,151 by 3:
40,471,151 ÷ 3 = 13,490,383.6667
If the quotient is a whole number, then 3 and 13,490,383.6667 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 | 40,471,151 | |
| -1 | -40,471,151 |
Let's try dividing by 4:
40,471,151 ÷ 4 = 10,117,787.75
If the quotient is a whole number, then 4 and 10,117,787.75 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 | 40,471,151 | |
| -1 | 40,471,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 421 | 443 | 2,947 | 3,101 | 13,051 | 13,733 | 91,357 | 96,131 | 186,503 | 1,305,521 | 5,781,593 | 40,471,151 |
| -1 | -7 | -31 | -217 | -421 | -443 | -2,947 | -3,101 | -13,051 | -13,733 | -91,357 | -96,131 | -186,503 | -1,305,521 | -5,781,593 | -40,471,151 |
