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 60,564,421, 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 | 60,564,421 | |
| -1 | -60,564,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,564,421.
Example:
1 x 60,564,421 = 60,564,421
and
-1 x -60,564,421 = 60,564,421
Notice both answers equal 60,564,421
With that explanation out of the way, let's continue. Next, we take the number 60,564,421 and divide it by 2:
60,564,421 ÷ 2 = 30,282,210.5
If the quotient is a whole number, then 2 and 30,282,210.5 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 | 60,564,421 | |
| -1 | -60,564,421 |
Now, we try dividing 60,564,421 by 3:
60,564,421 ÷ 3 = 20,188,140.3333
If the quotient is a whole number, then 3 and 20,188,140.3333 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 | 60,564,421 | |
| -1 | -60,564,421 |
Let's try dividing by 4:
60,564,421 ÷ 4 = 15,141,105.25
If the quotient is a whole number, then 4 and 15,141,105.25 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 | 60,564,421 | |
| -1 | 60,564,421 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 41 | 527 | 697 | 1,271 | 2,803 | 21,607 | 47,651 | 86,893 | 114,923 | 1,477,181 | 1,953,691 | 3,562,613 | 60,564,421 |
| -1 | -17 | -31 | -41 | -527 | -697 | -1,271 | -2,803 | -21,607 | -47,651 | -86,893 | -114,923 | -1,477,181 | -1,953,691 | -3,562,613 | -60,564,421 |
