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 61,563,635, 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 | 61,563,635 | |
| -1 | -61,563,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,563,635.
Example:
1 x 61,563,635 = 61,563,635
and
-1 x -61,563,635 = 61,563,635
Notice both answers equal 61,563,635
With that explanation out of the way, let's continue. Next, we take the number 61,563,635 and divide it by 2:
61,563,635 ÷ 2 = 30,781,817.5
If the quotient is a whole number, then 2 and 30,781,817.5 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 | 61,563,635 | |
| -1 | -61,563,635 |
Now, we try dividing 61,563,635 by 3:
61,563,635 ÷ 3 = 20,521,211.6667
If the quotient is a whole number, then 3 and 20,521,211.6667 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 | 61,563,635 | |
| -1 | -61,563,635 |
Let's try dividing by 4:
61,563,635 ÷ 4 = 15,390,908.75
If the quotient is a whole number, then 4 and 15,390,908.75 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 | 61,563,635 | |
| -1 | 61,563,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 199 | 995 | 1,393 | 6,965 | 8,839 | 44,195 | 61,873 | 309,365 | 1,758,961 | 8,794,805 | 12,312,727 | 61,563,635 |
| -1 | -5 | -7 | -35 | -199 | -995 | -1,393 | -6,965 | -8,839 | -44,195 | -61,873 | -309,365 | -1,758,961 | -8,794,805 | -12,312,727 | -61,563,635 |
