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 57,423,247, 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 | 57,423,247 | |
| -1 | -57,423,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,423,247.
Example:
1 x 57,423,247 = 57,423,247
and
-1 x -57,423,247 = 57,423,247
Notice both answers equal 57,423,247
With that explanation out of the way, let's continue. Next, we take the number 57,423,247 and divide it by 2:
57,423,247 ÷ 2 = 28,711,623.5
If the quotient is a whole number, then 2 and 28,711,623.5 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 | 57,423,247 | |
| -1 | -57,423,247 |
Now, we try dividing 57,423,247 by 3:
57,423,247 ÷ 3 = 19,141,082.3333
If the quotient is a whole number, then 3 and 19,141,082.3333 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 | 57,423,247 | |
| -1 | -57,423,247 |
Let's try dividing by 4:
57,423,247 ÷ 4 = 14,355,811.75
If the quotient is a whole number, then 4 and 14,355,811.75 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 | 57,423,247 | |
| -1 | 57,423,247 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 49 | 101 | 283 | 287 | 707 | 1,981 | 2,009 | 4,141 | 4,949 | 11,603 | 13,867 | 28,583 | 28,987 | 81,221 | 200,081 | 202,909 | 568,547 | 1,171,903 | 1,400,567 | 8,203,321 | 57,423,247 |
| -1 | -7 | -41 | -49 | -101 | -283 | -287 | -707 | -1,981 | -2,009 | -4,141 | -4,949 | -11,603 | -13,867 | -28,583 | -28,987 | -81,221 | -200,081 | -202,909 | -568,547 | -1,171,903 | -1,400,567 | -8,203,321 | -57,423,247 |
