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 54,310,531, 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 | 54,310,531 | |
| -1 | -54,310,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,310,531.
Example:
1 x 54,310,531 = 54,310,531
and
-1 x -54,310,531 = 54,310,531
Notice both answers equal 54,310,531
With that explanation out of the way, let's continue. Next, we take the number 54,310,531 and divide it by 2:
54,310,531 ÷ 2 = 27,155,265.5
If the quotient is a whole number, then 2 and 27,155,265.5 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 | 54,310,531 | |
| -1 | -54,310,531 |
Now, we try dividing 54,310,531 by 3:
54,310,531 ÷ 3 = 18,103,510.3333
If the quotient is a whole number, then 3 and 18,103,510.3333 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 | 54,310,531 | |
| -1 | -54,310,531 |
Let's try dividing by 4:
54,310,531 ÷ 4 = 13,577,632.75
If the quotient is a whole number, then 4 and 13,577,632.75 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 | 54,310,531 | |
| -1 | 54,310,531 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 53 | 209 | 583 | 1,007 | 4,903 | 11,077 | 53,933 | 93,157 | 259,859 | 1,024,727 | 2,858,449 | 4,937,321 | 54,310,531 |
| -1 | -11 | -19 | -53 | -209 | -583 | -1,007 | -4,903 | -11,077 | -53,933 | -93,157 | -259,859 | -1,024,727 | -2,858,449 | -4,937,321 | -54,310,531 |
