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 62,017,543, 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 | 62,017,543 | |
| -1 | -62,017,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,017,543.
Example:
1 x 62,017,543 = 62,017,543
and
-1 x -62,017,543 = 62,017,543
Notice both answers equal 62,017,543
With that explanation out of the way, let's continue. Next, we take the number 62,017,543 and divide it by 2:
62,017,543 ÷ 2 = 31,008,771.5
If the quotient is a whole number, then 2 and 31,008,771.5 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 | 62,017,543 | |
| -1 | -62,017,543 |
Now, we try dividing 62,017,543 by 3:
62,017,543 ÷ 3 = 20,672,514.3333
If the quotient is a whole number, then 3 and 20,672,514.3333 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 | 62,017,543 | |
| -1 | -62,017,543 |
Let's try dividing by 4:
62,017,543 ÷ 4 = 15,504,385.75
If the quotient is a whole number, then 4 and 15,504,385.75 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 | 62,017,543 | |
| -1 | 62,017,543 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 281 | 287 | 769 | 1,967 | 5,383 | 11,521 | 31,529 | 80,647 | 216,089 | 220,703 | 1,512,623 | 8,859,649 | 62,017,543 |
| -1 | -7 | -41 | -281 | -287 | -769 | -1,967 | -5,383 | -11,521 | -31,529 | -80,647 | -216,089 | -220,703 | -1,512,623 | -8,859,649 | -62,017,543 |
