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 53,174,615, 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 | 53,174,615 | |
| -1 | -53,174,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,174,615.
Example:
1 x 53,174,615 = 53,174,615
and
-1 x -53,174,615 = 53,174,615
Notice both answers equal 53,174,615
With that explanation out of the way, let's continue. Next, we take the number 53,174,615 and divide it by 2:
53,174,615 ÷ 2 = 26,587,307.5
If the quotient is a whole number, then 2 and 26,587,307.5 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 | 53,174,615 | |
| -1 | -53,174,615 |
Now, we try dividing 53,174,615 by 3:
53,174,615 ÷ 3 = 17,724,871.6667
If the quotient is a whole number, then 3 and 17,724,871.6667 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 | 53,174,615 | |
| -1 | -53,174,615 |
Let's try dividing by 4:
53,174,615 ÷ 4 = 13,293,653.75
If the quotient is a whole number, then 4 and 13,293,653.75 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 | 53,174,615 | |
| -1 | 53,174,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 793 | 3,965 | 13,411 | 67,055 | 174,343 | 818,071 | 871,715 | 4,090,355 | 10,634,923 | 53,174,615 |
| -1 | -5 | -13 | -61 | -65 | -305 | -793 | -3,965 | -13,411 | -67,055 | -174,343 | -818,071 | -871,715 | -4,090,355 | -10,634,923 | -53,174,615 |
