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 42,253,225, 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 | 42,253,225 | |
| -1 | -42,253,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,253,225.
Example:
1 x 42,253,225 = 42,253,225
and
-1 x -42,253,225 = 42,253,225
Notice both answers equal 42,253,225
With that explanation out of the way, let's continue. Next, we take the number 42,253,225 and divide it by 2:
42,253,225 ÷ 2 = 21,126,612.5
If the quotient is a whole number, then 2 and 21,126,612.5 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 | 42,253,225 | |
| -1 | -42,253,225 |
Now, we try dividing 42,253,225 by 3:
42,253,225 ÷ 3 = 14,084,408.3333
If the quotient is a whole number, then 3 and 14,084,408.3333 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 | 42,253,225 | |
| -1 | -42,253,225 |
Let's try dividing by 4:
42,253,225 ÷ 4 = 10,563,306.25
If the quotient is a whole number, then 4 and 10,563,306.25 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 | 42,253,225 | |
| -1 | 42,253,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 83 | 175 | 415 | 581 | 2,075 | 2,905 | 2,909 | 14,525 | 14,545 | 20,363 | 72,725 | 101,815 | 241,447 | 509,075 | 1,207,235 | 1,690,129 | 6,036,175 | 8,450,645 | 42,253,225 |
| -1 | -5 | -7 | -25 | -35 | -83 | -175 | -415 | -581 | -2,075 | -2,905 | -2,909 | -14,525 | -14,545 | -20,363 | -72,725 | -101,815 | -241,447 | -509,075 | -1,207,235 | -1,690,129 | -6,036,175 | -8,450,645 | -42,253,225 |
