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 53,070,545, 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 | 53,070,545 | |
| -1 | -53,070,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,070,545.
Example:
1 x 53,070,545 = 53,070,545
and
-1 x -53,070,545 = 53,070,545
Notice both answers equal 53,070,545
With that explanation out of the way, let's continue. Next, we take the number 53,070,545 and divide it by 2:
53,070,545 ÷ 2 = 26,535,272.5
If the quotient is a whole number, then 2 and 26,535,272.5 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 | 53,070,545 | |
| -1 | -53,070,545 |
Now, we try dividing 53,070,545 by 3:
53,070,545 ÷ 3 = 17,690,181.6667
If the quotient is a whole number, then 3 and 17,690,181.6667 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 | 53,070,545 | |
| -1 | -53,070,545 |
Let's try dividing by 4:
53,070,545 ÷ 4 = 13,267,636.25
If the quotient is a whole number, then 4 and 13,267,636.25 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 | 53,070,545 | |
| -1 | 53,070,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 41,953 | 209,765 | 461,483 | 964,919 | 2,307,415 | 4,824,595 | 10,614,109 | 53,070,545 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -41,953 | -209,765 | -461,483 | -964,919 | -2,307,415 | -4,824,595 | -10,614,109 | -53,070,545 |
