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 42,224,525, 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 | 42,224,525 | |
| -1 | -42,224,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,224,525.
Example:
1 x 42,224,525 = 42,224,525
and
-1 x -42,224,525 = 42,224,525
Notice both answers equal 42,224,525
With that explanation out of the way, let's continue. Next, we take the number 42,224,525 and divide it by 2:
42,224,525 ÷ 2 = 21,112,262.5
If the quotient is a whole number, then 2 and 21,112,262.5 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 | 42,224,525 | |
| -1 | -42,224,525 |
Now, we try dividing 42,224,525 by 3:
42,224,525 ÷ 3 = 14,074,841.6667
If the quotient is a whole number, then 3 and 14,074,841.6667 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 | 42,224,525 | |
| -1 | -42,224,525 |
Let's try dividing by 4:
42,224,525 ÷ 4 = 10,556,131.25
If the quotient is a whole number, then 4 and 10,556,131.25 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 | 42,224,525 | |
| -1 | 42,224,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 34,469 | 172,345 | 241,283 | 861,725 | 1,206,415 | 1,688,981 | 6,032,075 | 8,444,905 | 42,224,525 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -34,469 | -172,345 | -241,283 | -861,725 | -1,206,415 | -1,688,981 | -6,032,075 | -8,444,905 | -42,224,525 |
