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 42,123,025, 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 | 42,123,025 | |
| -1 | -42,123,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,123,025.
Example:
1 x 42,123,025 = 42,123,025
and
-1 x -42,123,025 = 42,123,025
Notice both answers equal 42,123,025
With that explanation out of the way, let's continue. Next, we take the number 42,123,025 and divide it by 2:
42,123,025 ÷ 2 = 21,061,512.5
If the quotient is a whole number, then 2 and 21,061,512.5 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 | 42,123,025 | |
| -1 | -42,123,025 |
Now, we try dividing 42,123,025 by 3:
42,123,025 ÷ 3 = 14,041,008.3333
If the quotient is a whole number, then 3 and 14,041,008.3333 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 | 42,123,025 | |
| -1 | -42,123,025 |
Let's try dividing by 4:
42,123,025 ÷ 4 = 10,530,756.25
If the quotient is a whole number, then 4 and 10,530,756.25 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 | 42,123,025 | |
| -1 | 42,123,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 85 | 119 | 175 | 425 | 595 | 2,975 | 14,159 | 70,795 | 99,113 | 240,703 | 353,975 | 495,565 | 1,203,515 | 1,684,921 | 2,477,825 | 6,017,575 | 8,424,605 | 42,123,025 |
| -1 | -5 | -7 | -17 | -25 | -35 | -85 | -119 | -175 | -425 | -595 | -2,975 | -14,159 | -70,795 | -99,113 | -240,703 | -353,975 | -495,565 | -1,203,515 | -1,684,921 | -2,477,825 | -6,017,575 | -8,424,605 | -42,123,025 |
