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 60,718,025, 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 | 60,718,025 | |
| -1 | -60,718,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,718,025.
Example:
1 x 60,718,025 = 60,718,025
and
-1 x -60,718,025 = 60,718,025
Notice both answers equal 60,718,025
With that explanation out of the way, let's continue. Next, we take the number 60,718,025 and divide it by 2:
60,718,025 ÷ 2 = 30,359,012.5
If the quotient is a whole number, then 2 and 30,359,012.5 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 | 60,718,025 | |
| -1 | -60,718,025 |
Now, we try dividing 60,718,025 by 3:
60,718,025 ÷ 3 = 20,239,341.6667
If the quotient is a whole number, then 3 and 20,239,341.6667 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 | 60,718,025 | |
| -1 | -60,718,025 |
Let's try dividing by 4:
60,718,025 ÷ 4 = 15,179,506.25
If the quotient is a whole number, then 4 and 15,179,506.25 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 | 60,718,025 | |
| -1 | 60,718,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 89 | 145 | 445 | 725 | 941 | 2,225 | 2,581 | 4,705 | 12,905 | 23,525 | 27,289 | 64,525 | 83,749 | 136,445 | 418,745 | 682,225 | 2,093,725 | 2,428,721 | 12,143,605 | 60,718,025 |
| -1 | -5 | -25 | -29 | -89 | -145 | -445 | -725 | -941 | -2,225 | -2,581 | -4,705 | -12,905 | -23,525 | -27,289 | -64,525 | -83,749 | -136,445 | -418,745 | -682,225 | -2,093,725 | -2,428,721 | -12,143,605 | -60,718,025 |
