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 3,975,565, 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 | 3,975,565 | |
| -1 | -3,975,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,975,565.
Example:
1 x 3,975,565 = 3,975,565
and
-1 x -3,975,565 = 3,975,565
Notice both answers equal 3,975,565
With that explanation out of the way, let's continue. Next, we take the number 3,975,565 and divide it by 2:
3,975,565 ÷ 2 = 1,987,782.5
If the quotient is a whole number, then 2 and 1,987,782.5 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 | 3,975,565 | |
| -1 | -3,975,565 |
Now, we try dividing 3,975,565 by 3:
3,975,565 ÷ 3 = 1,325,188.3333
If the quotient is a whole number, then 3 and 1,325,188.3333 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 | 3,975,565 | |
| -1 | -3,975,565 |
Let's try dividing by 4:
3,975,565 ÷ 4 = 993,891.25
If the quotient is a whole number, then 4 and 993,891.25 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 | 3,975,565 | |
| -1 | 3,975,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 43 | 55 | 205 | 215 | 451 | 473 | 1,681 | 1,763 | 2,255 | 2,365 | 8,405 | 8,815 | 18,491 | 19,393 | 72,283 | 92,455 | 96,965 | 361,415 | 795,113 | 3,975,565 |
| -1 | -5 | -11 | -41 | -43 | -55 | -205 | -215 | -451 | -473 | -1,681 | -1,763 | -2,255 | -2,365 | -8,405 | -8,815 | -18,491 | -19,393 | -72,283 | -92,455 | -96,965 | -361,415 | -795,113 | -3,975,565 |
