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 42,616,025, 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 | 42,616,025 | |
| -1 | -42,616,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,616,025.
Example:
1 x 42,616,025 = 42,616,025
and
-1 x -42,616,025 = 42,616,025
Notice both answers equal 42,616,025
With that explanation out of the way, let's continue. Next, we take the number 42,616,025 and divide it by 2:
42,616,025 ÷ 2 = 21,308,012.5
If the quotient is a whole number, then 2 and 21,308,012.5 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 | 42,616,025 | |
| -1 | -42,616,025 |
Now, we try dividing 42,616,025 by 3:
42,616,025 ÷ 3 = 14,205,341.6667
If the quotient is a whole number, then 3 and 14,205,341.6667 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 | 42,616,025 | |
| -1 | -42,616,025 |
Let's try dividing by 4:
42,616,025 ÷ 4 = 10,654,006.25
If the quotient is a whole number, then 4 and 10,654,006.25 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 | 42,616,025 | |
| -1 | 42,616,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 197 | 425 | 509 | 985 | 2,545 | 3,349 | 4,925 | 8,653 | 12,725 | 16,745 | 43,265 | 83,725 | 100,273 | 216,325 | 501,365 | 1,704,641 | 2,506,825 | 8,523,205 | 42,616,025 |
| -1 | -5 | -17 | -25 | -85 | -197 | -425 | -509 | -985 | -2,545 | -3,349 | -4,925 | -8,653 | -12,725 | -16,745 | -43,265 | -83,725 | -100,273 | -216,325 | -501,365 | -1,704,641 | -2,506,825 | -8,523,205 | -42,616,025 |
