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 55,478,461, 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 | 55,478,461 | |
| -1 | -55,478,461 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,478,461.
Example:
1 x 55,478,461 = 55,478,461
and
-1 x -55,478,461 = 55,478,461
Notice both answers equal 55,478,461
With that explanation out of the way, let's continue. Next, we take the number 55,478,461 and divide it by 2:
55,478,461 ÷ 2 = 27,739,230.5
If the quotient is a whole number, then 2 and 27,739,230.5 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 | 55,478,461 | |
| -1 | -55,478,461 |
Now, we try dividing 55,478,461 by 3:
55,478,461 ÷ 3 = 18,492,820.3333
If the quotient is a whole number, then 3 and 18,492,820.3333 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 | 55,478,461 | |
| -1 | -55,478,461 |
Let's try dividing by 4:
55,478,461 ÷ 4 = 13,869,615.25
If the quotient is a whole number, then 4 and 13,869,615.25 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 | 55,478,461 | |
| -1 | 55,478,461 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 79 | 437 | 1,501 | 1,607 | 1,817 | 30,533 | 34,523 | 36,961 | 126,953 | 702,259 | 2,412,107 | 2,919,919 | 55,478,461 |
| -1 | -19 | -23 | -79 | -437 | -1,501 | -1,607 | -1,817 | -30,533 | -34,523 | -36,961 | -126,953 | -702,259 | -2,412,107 | -2,919,919 | -55,478,461 |
