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 40,629,995, 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 | 40,629,995 | |
| -1 | -40,629,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,629,995.
Example:
1 x 40,629,995 = 40,629,995
and
-1 x -40,629,995 = 40,629,995
Notice both answers equal 40,629,995
With that explanation out of the way, let's continue. Next, we take the number 40,629,995 and divide it by 2:
40,629,995 ÷ 2 = 20,314,997.5
If the quotient is a whole number, then 2 and 20,314,997.5 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 | 40,629,995 | |
| -1 | -40,629,995 |
Now, we try dividing 40,629,995 by 3:
40,629,995 ÷ 3 = 13,543,331.6667
If the quotient is a whole number, then 3 and 13,543,331.6667 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 | 40,629,995 | |
| -1 | -40,629,995 |
Let's try dividing by 4:
40,629,995 ÷ 4 = 10,157,498.75
If the quotient is a whole number, then 4 and 10,157,498.75 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 | 40,629,995 | |
| -1 | 40,629,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 37,447 | 187,235 | 262,129 | 1,160,857 | 1,310,645 | 5,804,285 | 8,125,999 | 40,629,995 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -37,447 | -187,235 | -262,129 | -1,160,857 | -1,310,645 | -5,804,285 | -8,125,999 | -40,629,995 |
