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 61,554,127, 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 | 61,554,127 | |
| -1 | -61,554,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,554,127.
Example:
1 x 61,554,127 = 61,554,127
and
-1 x -61,554,127 = 61,554,127
Notice both answers equal 61,554,127
With that explanation out of the way, let's continue. Next, we take the number 61,554,127 and divide it by 2:
61,554,127 ÷ 2 = 30,777,063.5
If the quotient is a whole number, then 2 and 30,777,063.5 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 | 61,554,127 | |
| -1 | -61,554,127 |
Now, we try dividing 61,554,127 by 3:
61,554,127 ÷ 3 = 20,518,042.3333
If the quotient is a whole number, then 3 and 20,518,042.3333 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 | 61,554,127 | |
| -1 | -61,554,127 |
Let's try dividing by 4:
61,554,127 ÷ 4 = 15,388,531.75
If the quotient is a whole number, then 4 and 15,388,531.75 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 | 61,554,127 | |
| -1 | 61,554,127 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 271 | 431 | 527 | 4,607 | 7,327 | 8,401 | 13,361 | 116,801 | 142,817 | 227,137 | 1,985,617 | 3,620,831 | 61,554,127 |
| -1 | -17 | -31 | -271 | -431 | -527 | -4,607 | -7,327 | -8,401 | -13,361 | -116,801 | -142,817 | -227,137 | -1,985,617 | -3,620,831 | -61,554,127 |
