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 41,979,025, 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 | 41,979,025 | |
| -1 | -41,979,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,979,025.
Example:
1 x 41,979,025 = 41,979,025
and
-1 x -41,979,025 = 41,979,025
Notice both answers equal 41,979,025
With that explanation out of the way, let's continue. Next, we take the number 41,979,025 and divide it by 2:
41,979,025 ÷ 2 = 20,989,512.5
If the quotient is a whole number, then 2 and 20,989,512.5 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 | 41,979,025 | |
| -1 | -41,979,025 |
Now, we try dividing 41,979,025 by 3:
41,979,025 ÷ 3 = 13,993,008.3333
If the quotient is a whole number, then 3 and 13,993,008.3333 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 | 41,979,025 | |
| -1 | -41,979,025 |
Let's try dividing by 4:
41,979,025 ÷ 4 = 10,494,756.25
If the quotient is a whole number, then 4 and 10,494,756.25 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 | 41,979,025 | |
| -1 | 41,979,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 1,265 | 6,325 | 6,637 | 33,185 | 73,007 | 152,651 | 165,925 | 365,035 | 763,255 | 1,679,161 | 1,825,175 | 3,816,275 | 8,395,805 | 41,979,025 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -1,265 | -6,325 | -6,637 | -33,185 | -73,007 | -152,651 | -165,925 | -365,035 | -763,255 | -1,679,161 | -1,825,175 | -3,816,275 | -8,395,805 | -41,979,025 |
