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 40,546,751, 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 | 40,546,751 | |
| -1 | -40,546,751 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,546,751.
Example:
1 x 40,546,751 = 40,546,751
and
-1 x -40,546,751 = 40,546,751
Notice both answers equal 40,546,751
With that explanation out of the way, let's continue. Next, we take the number 40,546,751 and divide it by 2:
40,546,751 ÷ 2 = 20,273,375.5
If the quotient is a whole number, then 2 and 20,273,375.5 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 | 40,546,751 | |
| -1 | -40,546,751 |
Now, we try dividing 40,546,751 by 3:
40,546,751 ÷ 3 = 13,515,583.6667
If the quotient is a whole number, then 3 and 13,515,583.6667 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 | 40,546,751 | |
| -1 | -40,546,751 |
Let's try dividing by 4:
40,546,751 ÷ 4 = 10,136,687.75
If the quotient is a whole number, then 4 and 10,136,687.75 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 | 40,546,751 | |
| -1 | 40,546,751 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 71 | 119 | 497 | 1,207 | 4,799 | 8,449 | 33,593 | 81,583 | 340,729 | 571,081 | 2,385,103 | 5,792,393 | 40,546,751 |
| -1 | -7 | -17 | -71 | -119 | -497 | -1,207 | -4,799 | -8,449 | -33,593 | -81,583 | -340,729 | -571,081 | -2,385,103 | -5,792,393 | -40,546,751 |
