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 39,417,775, 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 | 39,417,775 | |
| -1 | -39,417,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,417,775.
Example:
1 x 39,417,775 = 39,417,775
and
-1 x -39,417,775 = 39,417,775
Notice both answers equal 39,417,775
With that explanation out of the way, let's continue. Next, we take the number 39,417,775 and divide it by 2:
39,417,775 ÷ 2 = 19,708,887.5
If the quotient is a whole number, then 2 and 19,708,887.5 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 | 39,417,775 | |
| -1 | -39,417,775 |
Now, we try dividing 39,417,775 by 3:
39,417,775 ÷ 3 = 13,139,258.3333
If the quotient is a whole number, then 3 and 13,139,258.3333 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 | 39,417,775 | |
| -1 | -39,417,775 |
Let's try dividing by 4:
39,417,775 ÷ 4 = 9,854,443.75
If the quotient is a whole number, then 4 and 9,854,443.75 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 | 39,417,775 | |
| -1 | 39,417,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 67 | 101 | 233 | 335 | 505 | 1,165 | 1,675 | 2,525 | 5,825 | 6,767 | 15,611 | 23,533 | 33,835 | 78,055 | 117,665 | 169,175 | 390,275 | 588,325 | 1,576,711 | 7,883,555 | 39,417,775 |
| -1 | -5 | -25 | -67 | -101 | -233 | -335 | -505 | -1,165 | -1,675 | -2,525 | -5,825 | -6,767 | -15,611 | -23,533 | -33,835 | -78,055 | -117,665 | -169,175 | -390,275 | -588,325 | -1,576,711 | -7,883,555 | -39,417,775 |
