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 7,657,225, 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 | 7,657,225 | |
| -1 | -7,657,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,657,225.
Example:
1 x 7,657,225 = 7,657,225
and
-1 x -7,657,225 = 7,657,225
Notice both answers equal 7,657,225
With that explanation out of the way, let's continue. Next, we take the number 7,657,225 and divide it by 2:
7,657,225 ÷ 2 = 3,828,612.5
If the quotient is a whole number, then 2 and 3,828,612.5 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 | 7,657,225 | |
| -1 | -7,657,225 |
Now, we try dividing 7,657,225 by 3:
7,657,225 ÷ 3 = 2,552,408.3333
If the quotient is a whole number, then 3 and 2,552,408.3333 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 | 7,657,225 | |
| -1 | -7,657,225 |
Let's try dividing by 4:
7,657,225 ÷ 4 = 1,914,306.25
If the quotient is a whole number, then 4 and 1,914,306.25 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 | 7,657,225 | |
| -1 | 7,657,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 43 | 85 | 215 | 419 | 425 | 731 | 1,075 | 2,095 | 3,655 | 7,123 | 10,475 | 18,017 | 18,275 | 35,615 | 90,085 | 178,075 | 306,289 | 450,425 | 1,531,445 | 7,657,225 |
| -1 | -5 | -17 | -25 | -43 | -85 | -215 | -419 | -425 | -731 | -1,075 | -2,095 | -3,655 | -7,123 | -10,475 | -18,017 | -18,275 | -35,615 | -90,085 | -178,075 | -306,289 | -450,425 | -1,531,445 | -7,657,225 |
