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 7,045,025, 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 | 7,045,025 | |
| -1 | -7,045,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,045,025.
Example:
1 x 7,045,025 = 7,045,025
and
-1 x -7,045,025 = 7,045,025
Notice both answers equal 7,045,025
With that explanation out of the way, let's continue. Next, we take the number 7,045,025 and divide it by 2:
7,045,025 ÷ 2 = 3,522,512.5
If the quotient is a whole number, then 2 and 3,522,512.5 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 | 7,045,025 | |
| -1 | -7,045,025 |
Now, we try dividing 7,045,025 by 3:
7,045,025 ÷ 3 = 2,348,341.6667
If the quotient is a whole number, then 3 and 2,348,341.6667 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 | 7,045,025 | |
| -1 | -7,045,025 |
Let's try dividing by 4:
7,045,025 ÷ 4 = 1,761,256.25
If the quotient is a whole number, then 4 and 1,761,256.25 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 | 7,045,025 | |
| -1 | 7,045,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 53 | 65 | 265 | 325 | 409 | 689 | 1,325 | 2,045 | 3,445 | 5,317 | 10,225 | 17,225 | 21,677 | 26,585 | 108,385 | 132,925 | 281,801 | 541,925 | 1,409,005 | 7,045,025 |
| -1 | -5 | -13 | -25 | -53 | -65 | -265 | -325 | -409 | -689 | -1,325 | -2,045 | -3,445 | -5,317 | -10,225 | -17,225 | -21,677 | -26,585 | -108,385 | -132,925 | -281,801 | -541,925 | -1,409,005 | -7,045,025 |
