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 55,621,705, 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 | 55,621,705 | |
| -1 | -55,621,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,621,705.
Example:
1 x 55,621,705 = 55,621,705
and
-1 x -55,621,705 = 55,621,705
Notice both answers equal 55,621,705
With that explanation out of the way, let's continue. Next, we take the number 55,621,705 and divide it by 2:
55,621,705 ÷ 2 = 27,810,852.5
If the quotient is a whole number, then 2 and 27,810,852.5 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 | 55,621,705 | |
| -1 | -55,621,705 |
Now, we try dividing 55,621,705 by 3:
55,621,705 ÷ 3 = 18,540,568.3333
If the quotient is a whole number, then 3 and 18,540,568.3333 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 | 55,621,705 | |
| -1 | -55,621,705 |
Let's try dividing by 4:
55,621,705 ÷ 4 = 13,905,426.25
If the quotient is a whole number, then 4 and 13,905,426.25 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 | 55,621,705 | |
| -1 | 55,621,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 529 | 1,237 | 1,955 | 2,645 | 6,185 | 8,993 | 21,029 | 28,451 | 44,965 | 105,145 | 142,255 | 483,667 | 654,373 | 2,418,335 | 3,271,865 | 11,124,341 | 55,621,705 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -529 | -1,237 | -1,955 | -2,645 | -6,185 | -8,993 | -21,029 | -28,451 | -44,965 | -105,145 | -142,255 | -483,667 | -654,373 | -2,418,335 | -3,271,865 | -11,124,341 | -55,621,705 |
