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 53,454,137, 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 | 53,454,137 | |
| -1 | -53,454,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,454,137.
Example:
1 x 53,454,137 = 53,454,137
and
-1 x -53,454,137 = 53,454,137
Notice both answers equal 53,454,137
With that explanation out of the way, let's continue. Next, we take the number 53,454,137 and divide it by 2:
53,454,137 ÷ 2 = 26,727,068.5
If the quotient is a whole number, then 2 and 26,727,068.5 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 | 53,454,137 | |
| -1 | -53,454,137 |
Now, we try dividing 53,454,137 by 3:
53,454,137 ÷ 3 = 17,818,045.6667
If the quotient is a whole number, then 3 and 17,818,045.6667 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 | 53,454,137 | |
| -1 | -53,454,137 |
Let's try dividing by 4:
53,454,137 ÷ 4 = 13,363,534.25
If the quotient is a whole number, then 4 and 13,363,534.25 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 | 53,454,137 | |
| -1 | 53,454,137 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 31 | 187 | 341 | 527 | 5,797 | 9,221 | 101,431 | 156,757 | 285,851 | 1,724,327 | 3,144,361 | 4,859,467 | 53,454,137 |
| -1 | -11 | -17 | -31 | -187 | -341 | -527 | -5,797 | -9,221 | -101,431 | -156,757 | -285,851 | -1,724,327 | -3,144,361 | -4,859,467 | -53,454,137 |
