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 15,522,325, 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 | 15,522,325 | |
| -1 | -15,522,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,522,325.
Example:
1 x 15,522,325 = 15,522,325
and
-1 x -15,522,325 = 15,522,325
Notice both answers equal 15,522,325
With that explanation out of the way, let's continue. Next, we take the number 15,522,325 and divide it by 2:
15,522,325 ÷ 2 = 7,761,162.5
If the quotient is a whole number, then 2 and 7,761,162.5 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 | 15,522,325 | |
| -1 | -15,522,325 |
Now, we try dividing 15,522,325 by 3:
15,522,325 ÷ 3 = 5,174,108.3333
If the quotient is a whole number, then 3 and 5,174,108.3333 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 | 15,522,325 | |
| -1 | -15,522,325 |
Let's try dividing by 4:
15,522,325 ÷ 4 = 3,880,581.25
If the quotient is a whole number, then 4 and 3,880,581.25 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 | 15,522,325 | |
| -1 | 15,522,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 2,275 | 6,823 | 34,115 | 47,761 | 88,699 | 170,575 | 238,805 | 443,495 | 620,893 | 1,194,025 | 2,217,475 | 3,104,465 | 15,522,325 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -2,275 | -6,823 | -34,115 | -47,761 | -88,699 | -170,575 | -238,805 | -443,495 | -620,893 | -1,194,025 | -2,217,475 | -3,104,465 | -15,522,325 |
