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 40,856,621, 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 | 40,856,621 | |
| -1 | -40,856,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,856,621.
Example:
1 x 40,856,621 = 40,856,621
and
-1 x -40,856,621 = 40,856,621
Notice both answers equal 40,856,621
With that explanation out of the way, let's continue. Next, we take the number 40,856,621 and divide it by 2:
40,856,621 ÷ 2 = 20,428,310.5
If the quotient is a whole number, then 2 and 20,428,310.5 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 | 40,856,621 | |
| -1 | -40,856,621 |
Now, we try dividing 40,856,621 by 3:
40,856,621 ÷ 3 = 13,618,873.6667
If the quotient is a whole number, then 3 and 13,618,873.6667 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 | 40,856,621 | |
| -1 | -40,856,621 |
Let's try dividing by 4:
40,856,621 ÷ 4 = 10,214,155.25
If the quotient is a whole number, then 4 and 10,214,155.25 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 | 40,856,621 | |
| -1 | 40,856,621 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 37 | 101 | 377 | 481 | 841 | 1,073 | 1,313 | 2,929 | 3,737 | 10,933 | 13,949 | 31,117 | 38,077 | 48,581 | 84,941 | 108,373 | 404,521 | 1,104,233 | 1,408,849 | 3,142,817 | 40,856,621 |
| -1 | -13 | -29 | -37 | -101 | -377 | -481 | -841 | -1,073 | -1,313 | -2,929 | -3,737 | -10,933 | -13,949 | -31,117 | -38,077 | -48,581 | -84,941 | -108,373 | -404,521 | -1,104,233 | -1,408,849 | -3,142,817 | -40,856,621 |
