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 62,612,131, 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 | 62,612,131 | |
| -1 | -62,612,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,612,131.
Example:
1 x 62,612,131 = 62,612,131
and
-1 x -62,612,131 = 62,612,131
Notice both answers equal 62,612,131
With that explanation out of the way, let's continue. Next, we take the number 62,612,131 and divide it by 2:
62,612,131 ÷ 2 = 31,306,065.5
If the quotient is a whole number, then 2 and 31,306,065.5 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 | 62,612,131 | |
| -1 | -62,612,131 |
Now, we try dividing 62,612,131 by 3:
62,612,131 ÷ 3 = 20,870,710.3333
If the quotient is a whole number, then 3 and 20,870,710.3333 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 | 62,612,131 | |
| -1 | -62,612,131 |
Let's try dividing by 4:
62,612,131 ÷ 4 = 15,653,032.75
If the quotient is a whole number, then 4 and 15,653,032.75 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 | 62,612,131 | |
| -1 | 62,612,131 |
If you did it right, you will end up with this table:
| 1 | 29 | 47 | 71 | 647 | 1,363 | 2,059 | 3,337 | 18,763 | 30,409 | 45,937 | 96,773 | 881,861 | 1,332,173 | 2,159,039 | 62,612,131 |
| -1 | -29 | -47 | -71 | -647 | -1,363 | -2,059 | -3,337 | -18,763 | -30,409 | -45,937 | -96,773 | -881,861 | -1,332,173 | -2,159,039 | -62,612,131 |
