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 55,645,577, 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 | 55,645,577 | |
| -1 | -55,645,577 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,645,577.
Example:
1 x 55,645,577 = 55,645,577
and
-1 x -55,645,577 = 55,645,577
Notice both answers equal 55,645,577
With that explanation out of the way, let's continue. Next, we take the number 55,645,577 and divide it by 2:
55,645,577 ÷ 2 = 27,822,788.5
If the quotient is a whole number, then 2 and 27,822,788.5 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 | 55,645,577 | |
| -1 | -55,645,577 |
Now, we try dividing 55,645,577 by 3:
55,645,577 ÷ 3 = 18,548,525.6667
If the quotient is a whole number, then 3 and 18,548,525.6667 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 | 55,645,577 | |
| -1 | -55,645,577 |
Let's try dividing by 4:
55,645,577 ÷ 4 = 13,911,394.25
If the quotient is a whole number, then 4 and 13,911,394.25 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 | 55,645,577 | |
| -1 | 55,645,577 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 67 | 377 | 871 | 1,943 | 2,203 | 25,259 | 28,639 | 63,887 | 147,601 | 830,531 | 1,918,813 | 4,280,429 | 55,645,577 |
| -1 | -13 | -29 | -67 | -377 | -871 | -1,943 | -2,203 | -25,259 | -28,639 | -63,887 | -147,601 | -830,531 | -1,918,813 | -4,280,429 | -55,645,577 |
