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 53,683,685, 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 | 53,683,685 | |
| -1 | -53,683,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,683,685.
Example:
1 x 53,683,685 = 53,683,685
and
-1 x -53,683,685 = 53,683,685
Notice both answers equal 53,683,685
With that explanation out of the way, let's continue. Next, we take the number 53,683,685 and divide it by 2:
53,683,685 ÷ 2 = 26,841,842.5
If the quotient is a whole number, then 2 and 26,841,842.5 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 | 53,683,685 | |
| -1 | -53,683,685 |
Now, we try dividing 53,683,685 by 3:
53,683,685 ÷ 3 = 17,894,561.6667
If the quotient is a whole number, then 3 and 17,894,561.6667 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 | 53,683,685 | |
| -1 | -53,683,685 |
Let's try dividing by 4:
53,683,685 ÷ 4 = 13,420,921.25
If the quotient is a whole number, then 4 and 13,420,921.25 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 | 53,683,685 | |
| -1 | 53,683,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 283 | 1,415 | 3,113 | 3,449 | 15,565 | 17,245 | 37,939 | 189,695 | 976,067 | 4,880,335 | 10,736,737 | 53,683,685 |
| -1 | -5 | -11 | -55 | -283 | -1,415 | -3,113 | -3,449 | -15,565 | -17,245 | -37,939 | -189,695 | -976,067 | -4,880,335 | -10,736,737 | -53,683,685 |
