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 60,607,225, 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 | 60,607,225 | |
| -1 | -60,607,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 60,607,225.
Example:
1 x 60,607,225 = 60,607,225
and
-1 x -60,607,225 = 60,607,225
Notice both answers equal 60,607,225
With that explanation out of the way, let's continue. Next, we take the number 60,607,225 and divide it by 2:
60,607,225 ÷ 2 = 30,303,612.5
If the quotient is a whole number, then 2 and 30,303,612.5 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 | 60,607,225 | |
| -1 | -60,607,225 |
Now, we try dividing 60,607,225 by 3:
60,607,225 ÷ 3 = 20,202,408.3333
If the quotient is a whole number, then 3 and 20,202,408.3333 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 | 60,607,225 | |
| -1 | -60,607,225 |
Let's try dividing by 4:
60,607,225 ÷ 4 = 15,151,806.25
If the quotient is a whole number, then 4 and 15,151,806.25 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 | 60,607,225 | |
| -1 | 60,607,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 41 | 175 | 205 | 287 | 1,025 | 1,435 | 7,175 | 8,447 | 42,235 | 59,129 | 211,175 | 295,645 | 346,327 | 1,478,225 | 1,731,635 | 2,424,289 | 8,658,175 | 12,121,445 | 60,607,225 |
| -1 | -5 | -7 | -25 | -35 | -41 | -175 | -205 | -287 | -1,025 | -1,435 | -7,175 | -8,447 | -42,235 | -59,129 | -211,175 | -295,645 | -346,327 | -1,478,225 | -1,731,635 | -2,424,289 | -8,658,175 | -12,121,445 | -60,607,225 |
