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 53,242,585, 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 | 53,242,585 | |
| -1 | -53,242,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,242,585.
Example:
1 x 53,242,585 = 53,242,585
and
-1 x -53,242,585 = 53,242,585
Notice both answers equal 53,242,585
With that explanation out of the way, let's continue. Next, we take the number 53,242,585 and divide it by 2:
53,242,585 ÷ 2 = 26,621,292.5
If the quotient is a whole number, then 2 and 26,621,292.5 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 | 53,242,585 | |
| -1 | -53,242,585 |
Now, we try dividing 53,242,585 by 3:
53,242,585 ÷ 3 = 17,747,528.3333
If the quotient is a whole number, then 3 and 17,747,528.3333 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 | 53,242,585 | |
| -1 | -53,242,585 |
Let's try dividing by 4:
53,242,585 ÷ 4 = 13,310,646.25
If the quotient is a whole number, then 4 and 13,310,646.25 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 | 53,242,585 | |
| -1 | 53,242,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 42,089 | 210,445 | 462,979 | 968,047 | 2,314,895 | 4,840,235 | 10,648,517 | 53,242,585 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -42,089 | -210,445 | -462,979 | -968,047 | -2,314,895 | -4,840,235 | -10,648,517 | -53,242,585 |
