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 3,740,581, 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 | 3,740,581 | |
| -1 | -3,740,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,740,581.
Example:
1 x 3,740,581 = 3,740,581
and
-1 x -3,740,581 = 3,740,581
Notice both answers equal 3,740,581
With that explanation out of the way, let's continue. Next, we take the number 3,740,581 and divide it by 2:
3,740,581 ÷ 2 = 1,870,290.5
If the quotient is a whole number, then 2 and 1,870,290.5 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 | 3,740,581 | |
| -1 | -3,740,581 |
Now, we try dividing 3,740,581 by 3:
3,740,581 ÷ 3 = 1,246,860.3333
If the quotient is a whole number, then 3 and 1,246,860.3333 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 | 3,740,581 | |
| -1 | -3,740,581 |
Let's try dividing by 4:
3,740,581 ÷ 4 = 935,145.25
If the quotient is a whole number, then 4 and 935,145.25 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 | 3,740,581 | |
| -1 | 3,740,581 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 61 | 89 | 689 | 793 | 1,157 | 3,233 | 4,717 | 5,429 | 42,029 | 61,321 | 70,577 | 287,737 | 3,740,581 |
| -1 | -13 | -53 | -61 | -89 | -689 | -793 | -1,157 | -3,233 | -4,717 | -5,429 | -42,029 | -61,321 | -70,577 | -287,737 | -3,740,581 |
