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 52,001,555, 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 | 52,001,555 | |
| -1 | -52,001,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,001,555.
Example:
1 x 52,001,555 = 52,001,555
and
-1 x -52,001,555 = 52,001,555
Notice both answers equal 52,001,555
With that explanation out of the way, let's continue. Next, we take the number 52,001,555 and divide it by 2:
52,001,555 ÷ 2 = 26,000,777.5
If the quotient is a whole number, then 2 and 26,000,777.5 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 | 52,001,555 | |
| -1 | -52,001,555 |
Now, we try dividing 52,001,555 by 3:
52,001,555 ÷ 3 = 17,333,851.6667
If the quotient is a whole number, then 3 and 17,333,851.6667 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 | 52,001,555 | |
| -1 | -52,001,555 |
Let's try dividing by 4:
52,001,555 ÷ 4 = 13,000,388.75
If the quotient is a whole number, then 4 and 13,000,388.75 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 | 52,001,555 | |
| -1 | 52,001,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 443 | 1,381 | 2,215 | 6,905 | 7,531 | 23,477 | 37,655 | 117,385 | 611,783 | 3,058,915 | 10,400,311 | 52,001,555 |
| -1 | -5 | -17 | -85 | -443 | -1,381 | -2,215 | -6,905 | -7,531 | -23,477 | -37,655 | -117,385 | -611,783 | -3,058,915 | -10,400,311 | -52,001,555 |
