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 53,722,505, 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 | 53,722,505 | |
| -1 | -53,722,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,722,505.
Example:
1 x 53,722,505 = 53,722,505
and
-1 x -53,722,505 = 53,722,505
Notice both answers equal 53,722,505
With that explanation out of the way, let's continue. Next, we take the number 53,722,505 and divide it by 2:
53,722,505 ÷ 2 = 26,861,252.5
If the quotient is a whole number, then 2 and 26,861,252.5 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 | 53,722,505 | |
| -1 | -53,722,505 |
Now, we try dividing 53,722,505 by 3:
53,722,505 ÷ 3 = 17,907,501.6667
If the quotient is a whole number, then 3 and 17,907,501.6667 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 | 53,722,505 | |
| -1 | -53,722,505 |
Let's try dividing by 4:
53,722,505 ÷ 4 = 13,430,626.25
If the quotient is a whole number, then 4 and 13,430,626.25 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 | 53,722,505 | |
| -1 | 53,722,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 71 | 205 | 355 | 2,911 | 3,691 | 14,555 | 18,455 | 151,331 | 262,061 | 756,655 | 1,310,305 | 10,744,501 | 53,722,505 |
| -1 | -5 | -41 | -71 | -205 | -355 | -2,911 | -3,691 | -14,555 | -18,455 | -151,331 | -262,061 | -756,655 | -1,310,305 | -10,744,501 | -53,722,505 |
