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 62,644,145, 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 | 62,644,145 | |
| -1 | -62,644,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,644,145.
Example:
1 x 62,644,145 = 62,644,145
and
-1 x -62,644,145 = 62,644,145
Notice both answers equal 62,644,145
With that explanation out of the way, let's continue. Next, we take the number 62,644,145 and divide it by 2:
62,644,145 ÷ 2 = 31,322,072.5
If the quotient is a whole number, then 2 and 31,322,072.5 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 | 62,644,145 | |
| -1 | -62,644,145 |
Now, we try dividing 62,644,145 by 3:
62,644,145 ÷ 3 = 20,881,381.6667
If the quotient is a whole number, then 3 and 20,881,381.6667 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 | 62,644,145 | |
| -1 | -62,644,145 |
Let's try dividing by 4:
62,644,145 ÷ 4 = 15,661,036.25
If the quotient is a whole number, then 4 and 15,661,036.25 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 | 62,644,145 | |
| -1 | 62,644,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 53 | 185 | 265 | 1,961 | 6,389 | 9,805 | 31,945 | 236,393 | 338,617 | 1,181,965 | 1,693,085 | 12,528,829 | 62,644,145 |
| -1 | -5 | -37 | -53 | -185 | -265 | -1,961 | -6,389 | -9,805 | -31,945 | -236,393 | -338,617 | -1,181,965 | -1,693,085 | -12,528,829 | -62,644,145 |
