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 61,423,135, 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 | 61,423,135 | |
| -1 | -61,423,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,423,135.
Example:
1 x 61,423,135 = 61,423,135
and
-1 x -61,423,135 = 61,423,135
Notice both answers equal 61,423,135
With that explanation out of the way, let's continue. Next, we take the number 61,423,135 and divide it by 2:
61,423,135 ÷ 2 = 30,711,567.5
If the quotient is a whole number, then 2 and 30,711,567.5 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 | 61,423,135 | |
| -1 | -61,423,135 |
Now, we try dividing 61,423,135 by 3:
61,423,135 ÷ 3 = 20,474,378.3333
If the quotient is a whole number, then 3 and 20,474,378.3333 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 | 61,423,135 | |
| -1 | -61,423,135 |
Let's try dividing by 4:
61,423,135 ÷ 4 = 15,355,783.75
If the quotient is a whole number, then 4 and 15,355,783.75 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 | 61,423,135 | |
| -1 | 61,423,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 109 | 215 | 545 | 2,621 | 4,687 | 13,105 | 23,435 | 112,703 | 285,689 | 563,515 | 1,428,445 | 12,284,627 | 61,423,135 |
| -1 | -5 | -43 | -109 | -215 | -545 | -2,621 | -4,687 | -13,105 | -23,435 | -112,703 | -285,689 | -563,515 | -1,428,445 | -12,284,627 | -61,423,135 |
