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 47,610,389, 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 | 47,610,389 | |
| -1 | -47,610,389 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,610,389.
Example:
1 x 47,610,389 = 47,610,389
and
-1 x -47,610,389 = 47,610,389
Notice both answers equal 47,610,389
With that explanation out of the way, let's continue. Next, we take the number 47,610,389 and divide it by 2:
47,610,389 ÷ 2 = 23,805,194.5
If the quotient is a whole number, then 2 and 23,805,194.5 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 | 47,610,389 | |
| -1 | -47,610,389 |
Now, we try dividing 47,610,389 by 3:
47,610,389 ÷ 3 = 15,870,129.6667
If the quotient is a whole number, then 3 and 15,870,129.6667 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 | 47,610,389 | |
| -1 | -47,610,389 |
Let's try dividing by 4:
47,610,389 ÷ 4 = 11,902,597.25
If the quotient is a whole number, then 4 and 11,902,597.25 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 | 47,610,389 | |
| -1 | 47,610,389 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 47 | 797 | 1,271 | 1,457 | 1,927 | 24,707 | 32,677 | 37,459 | 59,737 | 1,012,987 | 1,161,229 | 1,535,819 | 47,610,389 |
| -1 | -31 | -41 | -47 | -797 | -1,271 | -1,457 | -1,927 | -24,707 | -32,677 | -37,459 | -59,737 | -1,012,987 | -1,161,229 | -1,535,819 | -47,610,389 |
