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 53,374,165, 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 | 53,374,165 | |
| -1 | -53,374,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,374,165.
Example:
1 x 53,374,165 = 53,374,165
and
-1 x -53,374,165 = 53,374,165
Notice both answers equal 53,374,165
With that explanation out of the way, let's continue. Next, we take the number 53,374,165 and divide it by 2:
53,374,165 ÷ 2 = 26,687,082.5
If the quotient is a whole number, then 2 and 26,687,082.5 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 | 53,374,165 | |
| -1 | -53,374,165 |
Now, we try dividing 53,374,165 by 3:
53,374,165 ÷ 3 = 17,791,388.3333
If the quotient is a whole number, then 3 and 17,791,388.3333 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 | 53,374,165 | |
| -1 | -53,374,165 |
Let's try dividing by 4:
53,374,165 ÷ 4 = 13,343,541.25
If the quotient is a whole number, then 4 and 13,343,541.25 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 | 53,374,165 | |
| -1 | 53,374,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 22,193 | 110,965 | 288,509 | 821,141 | 1,442,545 | 4,105,705 | 10,674,833 | 53,374,165 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -22,193 | -110,965 | -288,509 | -821,141 | -1,442,545 | -4,105,705 | -10,674,833 | -53,374,165 |
