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 74,083,025, 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 | 74,083,025 | |
| -1 | -74,083,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,083,025.
Example:
1 x 74,083,025 = 74,083,025
and
-1 x -74,083,025 = 74,083,025
Notice both answers equal 74,083,025
With that explanation out of the way, let's continue. Next, we take the number 74,083,025 and divide it by 2:
74,083,025 ÷ 2 = 37,041,512.5
If the quotient is a whole number, then 2 and 37,041,512.5 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 | 74,083,025 | |
| -1 | -74,083,025 |
Now, we try dividing 74,083,025 by 3:
74,083,025 ÷ 3 = 24,694,341.6667
If the quotient is a whole number, then 3 and 24,694,341.6667 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 | 74,083,025 | |
| -1 | -74,083,025 |
Let's try dividing by 4:
74,083,025 ÷ 4 = 18,520,756.25
If the quotient is a whole number, then 4 and 18,520,756.25 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 | 74,083,025 | |
| -1 | 74,083,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 31 | 85 | 155 | 425 | 527 | 775 | 2,635 | 5,623 | 13,175 | 28,115 | 95,591 | 140,575 | 174,313 | 477,955 | 871,565 | 2,389,775 | 2,963,321 | 4,357,825 | 14,816,605 | 74,083,025 |
| -1 | -5 | -17 | -25 | -31 | -85 | -155 | -425 | -527 | -775 | -2,635 | -5,623 | -13,175 | -28,115 | -95,591 | -140,575 | -174,313 | -477,955 | -871,565 | -2,389,775 | -2,963,321 | -4,357,825 | -14,816,605 | -74,083,025 |
