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 61,660,435, 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 | 61,660,435 | |
| -1 | -61,660,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,660,435.
Example:
1 x 61,660,435 = 61,660,435
and
-1 x -61,660,435 = 61,660,435
Notice both answers equal 61,660,435
With that explanation out of the way, let's continue. Next, we take the number 61,660,435 and divide it by 2:
61,660,435 ÷ 2 = 30,830,217.5
If the quotient is a whole number, then 2 and 30,830,217.5 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 | 61,660,435 | |
| -1 | -61,660,435 |
Now, we try dividing 61,660,435 by 3:
61,660,435 ÷ 3 = 20,553,478.3333
If the quotient is a whole number, then 3 and 20,553,478.3333 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 | 61,660,435 | |
| -1 | -61,660,435 |
Let's try dividing by 4:
61,660,435 ÷ 4 = 15,415,108.75
If the quotient is a whole number, then 4 and 15,415,108.75 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 | 61,660,435 | |
| -1 | 61,660,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 103 | 335 | 515 | 1,787 | 6,901 | 8,935 | 34,505 | 119,729 | 184,061 | 598,645 | 920,305 | 12,332,087 | 61,660,435 |
| -1 | -5 | -67 | -103 | -335 | -515 | -1,787 | -6,901 | -8,935 | -34,505 | -119,729 | -184,061 | -598,645 | -920,305 | -12,332,087 | -61,660,435 |
