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 61,764,409, 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 | 61,764,409 | |
| -1 | -61,764,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,764,409.
Example:
1 x 61,764,409 = 61,764,409
and
-1 x -61,764,409 = 61,764,409
Notice both answers equal 61,764,409
With that explanation out of the way, let's continue. Next, we take the number 61,764,409 and divide it by 2:
61,764,409 ÷ 2 = 30,882,204.5
If the quotient is a whole number, then 2 and 30,882,204.5 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 | 61,764,409 | |
| -1 | -61,764,409 |
Now, we try dividing 61,764,409 by 3:
61,764,409 ÷ 3 = 20,588,136.3333
If the quotient is a whole number, then 3 and 20,588,136.3333 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 | 61,764,409 | |
| -1 | -61,764,409 |
Let's try dividing by 4:
61,764,409 ÷ 4 = 15,441,102.25
If the quotient is a whole number, then 4 and 15,441,102.25 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 | 61,764,409 | |
| -1 | 61,764,409 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 287 | 307 | 701 | 2,149 | 4,907 | 12,587 | 28,741 | 88,109 | 201,187 | 215,207 | 1,506,449 | 8,823,487 | 61,764,409 |
| -1 | -7 | -41 | -287 | -307 | -701 | -2,149 | -4,907 | -12,587 | -28,741 | -88,109 | -201,187 | -215,207 | -1,506,449 | -8,823,487 | -61,764,409 |
