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 61,713,115, 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 | 61,713,115 | |
| -1 | -61,713,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,713,115.
Example:
1 x 61,713,115 = 61,713,115
and
-1 x -61,713,115 = 61,713,115
Notice both answers equal 61,713,115
With that explanation out of the way, let's continue. Next, we take the number 61,713,115 and divide it by 2:
61,713,115 ÷ 2 = 30,856,557.5
If the quotient is a whole number, then 2 and 30,856,557.5 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 | 61,713,115 | |
| -1 | -61,713,115 |
Now, we try dividing 61,713,115 by 3:
61,713,115 ÷ 3 = 20,571,038.3333
If the quotient is a whole number, then 3 and 20,571,038.3333 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 | 61,713,115 | |
| -1 | -61,713,115 |
Let's try dividing by 4:
61,713,115 ÷ 4 = 15,428,278.75
If the quotient is a whole number, then 4 and 15,428,278.75 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 | 61,713,115 | |
| -1 | 61,713,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 59 | 235 | 295 | 2,773 | 4,451 | 13,865 | 22,255 | 209,197 | 262,609 | 1,045,985 | 1,313,045 | 12,342,623 | 61,713,115 |
| -1 | -5 | -47 | -59 | -235 | -295 | -2,773 | -4,451 | -13,865 | -22,255 | -209,197 | -262,609 | -1,045,985 | -1,313,045 | -12,342,623 | -61,713,115 |
