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 56,220,073, 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 | 56,220,073 | |
| -1 | -56,220,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,220,073.
Example:
1 x 56,220,073 = 56,220,073
and
-1 x -56,220,073 = 56,220,073
Notice both answers equal 56,220,073
With that explanation out of the way, let's continue. Next, we take the number 56,220,073 and divide it by 2:
56,220,073 ÷ 2 = 28,110,036.5
If the quotient is a whole number, then 2 and 28,110,036.5 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 | 56,220,073 | |
| -1 | -56,220,073 |
Now, we try dividing 56,220,073 by 3:
56,220,073 ÷ 3 = 18,740,024.3333
If the quotient is a whole number, then 3 and 18,740,024.3333 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 | 56,220,073 | |
| -1 | -56,220,073 |
Let's try dividing by 4:
56,220,073 ÷ 4 = 14,055,018.25
If the quotient is a whole number, then 4 and 14,055,018.25 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 | 56,220,073 | |
| -1 | 56,220,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 2,093 | 26,861 | 188,027 | 349,193 | 617,803 | 2,444,351 | 4,324,621 | 8,031,439 | 56,220,073 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -2,093 | -26,861 | -188,027 | -349,193 | -617,803 | -2,444,351 | -4,324,621 | -8,031,439 | -56,220,073 |
