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 53,014,451, 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 | 53,014,451 | |
| -1 | -53,014,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,014,451.
Example:
1 x 53,014,451 = 53,014,451
and
-1 x -53,014,451 = 53,014,451
Notice both answers equal 53,014,451
With that explanation out of the way, let's continue. Next, we take the number 53,014,451 and divide it by 2:
53,014,451 ÷ 2 = 26,507,225.5
If the quotient is a whole number, then 2 and 26,507,225.5 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 | 53,014,451 | |
| -1 | -53,014,451 |
Now, we try dividing 53,014,451 by 3:
53,014,451 ÷ 3 = 17,671,483.6667
If the quotient is a whole number, then 3 and 17,671,483.6667 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 | 53,014,451 | |
| -1 | -53,014,451 |
Let's try dividing by 4:
53,014,451 ÷ 4 = 13,253,612.75
If the quotient is a whole number, then 4 and 13,253,612.75 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 | 53,014,451 | |
| -1 | 53,014,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 79 | 259 | 553 | 2,591 | 2,923 | 18,137 | 20,461 | 95,867 | 204,689 | 671,069 | 1,432,823 | 7,573,493 | 53,014,451 |
| -1 | -7 | -37 | -79 | -259 | -553 | -2,591 | -2,923 | -18,137 | -20,461 | -95,867 | -204,689 | -671,069 | -1,432,823 | -7,573,493 | -53,014,451 |
