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 56,402,401, 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 | 56,402,401 | |
| -1 | -56,402,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,402,401.
Example:
1 x 56,402,401 = 56,402,401
and
-1 x -56,402,401 = 56,402,401
Notice both answers equal 56,402,401
With that explanation out of the way, let's continue. Next, we take the number 56,402,401 and divide it by 2:
56,402,401 ÷ 2 = 28,201,200.5
If the quotient is a whole number, then 2 and 28,201,200.5 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 | 56,402,401 | |
| -1 | -56,402,401 |
Now, we try dividing 56,402,401 by 3:
56,402,401 ÷ 3 = 18,800,800.3333
If the quotient is a whole number, then 3 and 18,800,800.3333 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 | 56,402,401 | |
| -1 | -56,402,401 |
Let's try dividing by 4:
56,402,401 ÷ 4 = 14,100,600.25
If the quotient is a whole number, then 4 and 14,100,600.25 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 | 56,402,401 | |
| -1 | 56,402,401 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 163 | 379 | 913 | 1,793 | 4,169 | 13,529 | 31,457 | 61,777 | 148,819 | 346,027 | 679,547 | 5,127,491 | 56,402,401 |
| -1 | -11 | -83 | -163 | -379 | -913 | -1,793 | -4,169 | -13,529 | -31,457 | -61,777 | -148,819 | -346,027 | -679,547 | -5,127,491 | -56,402,401 |
