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 3,538,711, 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 | 3,538,711 | |
| -1 | -3,538,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,538,711.
Example:
1 x 3,538,711 = 3,538,711
and
-1 x -3,538,711 = 3,538,711
Notice both answers equal 3,538,711
With that explanation out of the way, let's continue. Next, we take the number 3,538,711 and divide it by 2:
3,538,711 ÷ 2 = 1,769,355.5
If the quotient is a whole number, then 2 and 1,769,355.5 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 | 3,538,711 | |
| -1 | -3,538,711 |
Now, we try dividing 3,538,711 by 3:
3,538,711 ÷ 3 = 1,179,570.3333
If the quotient is a whole number, then 3 and 1,179,570.3333 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 | 3,538,711 | |
| -1 | -3,538,711 |
Let's try dividing by 4:
3,538,711 ÷ 4 = 884,677.75
If the quotient is a whole number, then 4 and 884,677.75 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 | 3,538,711 | |
| -1 | 3,538,711 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 71 | 197 | 253 | 781 | 1,633 | 2,167 | 4,531 | 13,987 | 17,963 | 49,841 | 153,857 | 321,701 | 3,538,711 |
| -1 | -11 | -23 | -71 | -197 | -253 | -781 | -1,633 | -2,167 | -4,531 | -13,987 | -17,963 | -49,841 | -153,857 | -321,701 | -3,538,711 |
