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 74,054,225, 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 | 74,054,225 | |
| -1 | -74,054,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,054,225.
Example:
1 x 74,054,225 = 74,054,225
and
-1 x -74,054,225 = 74,054,225
Notice both answers equal 74,054,225
With that explanation out of the way, let's continue. Next, we take the number 74,054,225 and divide it by 2:
74,054,225 ÷ 2 = 37,027,112.5
If the quotient is a whole number, then 2 and 37,027,112.5 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 | 74,054,225 | |
| -1 | -74,054,225 |
Now, we try dividing 74,054,225 by 3:
74,054,225 ÷ 3 = 24,684,741.6667
If the quotient is a whole number, then 3 and 24,684,741.6667 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 | 74,054,225 | |
| -1 | -74,054,225 |
Let's try dividing by 4:
74,054,225 ÷ 4 = 18,513,556.25
If the quotient is a whole number, then 4 and 18,513,556.25 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 | 74,054,225 | |
| -1 | 74,054,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 263 | 1,315 | 1,609 | 1,841 | 6,575 | 8,045 | 9,205 | 11,263 | 40,225 | 46,025 | 56,315 | 281,575 | 423,167 | 2,115,835 | 2,962,169 | 10,579,175 | 14,810,845 | 74,054,225 |
| -1 | -5 | -7 | -25 | -35 | -175 | -263 | -1,315 | -1,609 | -1,841 | -6,575 | -8,045 | -9,205 | -11,263 | -40,225 | -46,025 | -56,315 | -281,575 | -423,167 | -2,115,835 | -2,962,169 | -10,579,175 | -14,810,845 | -74,054,225 |
