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 3,487,465, 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 | 3,487,465 | |
| -1 | -3,487,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,487,465.
Example:
1 x 3,487,465 = 3,487,465
and
-1 x -3,487,465 = 3,487,465
Notice both answers equal 3,487,465
With that explanation out of the way, let's continue. Next, we take the number 3,487,465 and divide it by 2:
3,487,465 ÷ 2 = 1,743,732.5
If the quotient is a whole number, then 2 and 1,743,732.5 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 | 3,487,465 | |
| -1 | -3,487,465 |
Now, we try dividing 3,487,465 by 3:
3,487,465 ÷ 3 = 1,162,488.3333
If the quotient is a whole number, then 3 and 1,162,488.3333 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 | 3,487,465 | |
| -1 | -3,487,465 |
Let's try dividing by 4:
3,487,465 ÷ 4 = 871,866.25
If the quotient is a whole number, then 4 and 871,866.25 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 | 3,487,465 | |
| -1 | 3,487,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 89 | 445 | 461 | 1,513 | 2,305 | 7,565 | 7,837 | 39,185 | 41,029 | 205,145 | 697,493 | 3,487,465 |
| -1 | -5 | -17 | -85 | -89 | -445 | -461 | -1,513 | -2,305 | -7,565 | -7,837 | -39,185 | -41,029 | -205,145 | -697,493 | -3,487,465 |
