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 60,253,501, 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 | 60,253,501 | |
| -1 | -60,253,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,253,501.
Example:
1 x 60,253,501 = 60,253,501
and
-1 x -60,253,501 = 60,253,501
Notice both answers equal 60,253,501
With that explanation out of the way, let's continue. Next, we take the number 60,253,501 and divide it by 2:
60,253,501 ÷ 2 = 30,126,750.5
If the quotient is a whole number, then 2 and 30,126,750.5 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 | 60,253,501 | |
| -1 | -60,253,501 |
Now, we try dividing 60,253,501 by 3:
60,253,501 ÷ 3 = 20,084,500.3333
If the quotient is a whole number, then 3 and 20,084,500.3333 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 | 60,253,501 | |
| -1 | -60,253,501 |
Let's try dividing by 4:
60,253,501 ÷ 4 = 15,063,375.25
If the quotient is a whole number, then 4 and 15,063,375.25 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 | 60,253,501 | |
| -1 | 60,253,501 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 2,849 | 21,149 | 148,043 | 232,639 | 782,513 | 1,628,473 | 5,477,591 | 8,607,643 | 60,253,501 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -2,849 | -21,149 | -148,043 | -232,639 | -782,513 | -1,628,473 | -5,477,591 | -8,607,643 | -60,253,501 |
