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 53,802,451, 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 | 53,802,451 | |
| -1 | -53,802,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,802,451.
Example:
1 x 53,802,451 = 53,802,451
and
-1 x -53,802,451 = 53,802,451
Notice both answers equal 53,802,451
With that explanation out of the way, let's continue. Next, we take the number 53,802,451 and divide it by 2:
53,802,451 ÷ 2 = 26,901,225.5
If the quotient is a whole number, then 2 and 26,901,225.5 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 | 53,802,451 | |
| -1 | -53,802,451 |
Now, we try dividing 53,802,451 by 3:
53,802,451 ÷ 3 = 17,934,150.3333
If the quotient is a whole number, then 3 and 17,934,150.3333 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 | 53,802,451 | |
| -1 | -53,802,451 |
Let's try dividing by 4:
53,802,451 ÷ 4 = 13,450,612.75
If the quotient is a whole number, then 4 and 13,450,612.75 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 | 53,802,451 | |
| -1 | 53,802,451 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 71 | 701 | 1,081 | 1,633 | 3,337 | 16,123 | 32,947 | 49,771 | 76,751 | 757,781 | 1,144,733 | 2,339,237 | 53,802,451 |
| -1 | -23 | -47 | -71 | -701 | -1,081 | -1,633 | -3,337 | -16,123 | -32,947 | -49,771 | -76,751 | -757,781 | -1,144,733 | -2,339,237 | -53,802,451 |
