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 3,875,875, 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 | 3,875,875 | |
| -1 | -3,875,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,875,875.
Example:
1 x 3,875,875 = 3,875,875
and
-1 x -3,875,875 = 3,875,875
Notice both answers equal 3,875,875
With that explanation out of the way, let's continue. Next, we take the number 3,875,875 and divide it by 2:
3,875,875 ÷ 2 = 1,937,937.5
If the quotient is a whole number, then 2 and 1,937,937.5 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 | 3,875,875 | |
| -1 | -3,875,875 |
Now, we try dividing 3,875,875 by 3:
3,875,875 ÷ 3 = 1,291,958.3333
If the quotient is a whole number, then 3 and 1,291,958.3333 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 | 3,875,875 | |
| -1 | -3,875,875 |
Let's try dividing by 4:
3,875,875 ÷ 4 = 968,968.75
If the quotient is a whole number, then 4 and 968,968.75 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 | 3,875,875 | |
| -1 | 3,875,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 101 | 125 | 307 | 505 | 1,535 | 2,525 | 7,675 | 12,625 | 31,007 | 38,375 | 155,035 | 775,175 | 3,875,875 |
| -1 | -5 | -25 | -101 | -125 | -307 | -505 | -1,535 | -2,525 | -7,675 | -12,625 | -31,007 | -38,375 | -155,035 | -775,175 | -3,875,875 |
