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 62,740,069, 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 | 62,740,069 | |
| -1 | -62,740,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,740,069.
Example:
1 x 62,740,069 = 62,740,069
and
-1 x -62,740,069 = 62,740,069
Notice both answers equal 62,740,069
With that explanation out of the way, let's continue. Next, we take the number 62,740,069 and divide it by 2:
62,740,069 ÷ 2 = 31,370,034.5
If the quotient is a whole number, then 2 and 31,370,034.5 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 | 62,740,069 | |
| -1 | -62,740,069 |
Now, we try dividing 62,740,069 by 3:
62,740,069 ÷ 3 = 20,913,356.3333
If the quotient is a whole number, then 3 and 20,913,356.3333 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 | 62,740,069 | |
| -1 | -62,740,069 |
Let's try dividing by 4:
62,740,069 ÷ 4 = 15,685,017.25
If the quotient is a whole number, then 4 and 15,685,017.25 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 | 62,740,069 | |
| -1 | 62,740,069 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 73 | 413 | 511 | 2,081 | 4,307 | 14,567 | 30,149 | 122,779 | 151,913 | 859,453 | 1,063,391 | 8,962,867 | 62,740,069 |
| -1 | -7 | -59 | -73 | -413 | -511 | -2,081 | -4,307 | -14,567 | -30,149 | -122,779 | -151,913 | -859,453 | -1,063,391 | -8,962,867 | -62,740,069 |
