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 60,671,513, 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 | 60,671,513 | |
| -1 | -60,671,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,671,513.
Example:
1 x 60,671,513 = 60,671,513
and
-1 x -60,671,513 = 60,671,513
Notice both answers equal 60,671,513
With that explanation out of the way, let's continue. Next, we take the number 60,671,513 and divide it by 2:
60,671,513 ÷ 2 = 30,335,756.5
If the quotient is a whole number, then 2 and 30,335,756.5 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 | 60,671,513 | |
| -1 | -60,671,513 |
Now, we try dividing 60,671,513 by 3:
60,671,513 ÷ 3 = 20,223,837.6667
If the quotient is a whole number, then 3 and 20,223,837.6667 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 | 60,671,513 | |
| -1 | -60,671,513 |
Let's try dividing by 4:
60,671,513 ÷ 4 = 15,167,878.25
If the quotient is a whole number, then 4 and 15,167,878.25 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 | 60,671,513 | |
| -1 | 60,671,513 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 179 | 287 | 1,181 | 1,253 | 7,339 | 8,267 | 48,421 | 51,373 | 211,399 | 338,947 | 1,479,793 | 8,667,359 | 60,671,513 |
| -1 | -7 | -41 | -179 | -287 | -1,181 | -1,253 | -7,339 | -8,267 | -48,421 | -51,373 | -211,399 | -338,947 | -1,479,793 | -8,667,359 | -60,671,513 |
