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 52,142,657, 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 | 52,142,657 | |
| -1 | -52,142,657 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,142,657.
Example:
1 x 52,142,657 = 52,142,657
and
-1 x -52,142,657 = 52,142,657
Notice both answers equal 52,142,657
With that explanation out of the way, let's continue. Next, we take the number 52,142,657 and divide it by 2:
52,142,657 ÷ 2 = 26,071,328.5
If the quotient is a whole number, then 2 and 26,071,328.5 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 | 52,142,657 | |
| -1 | -52,142,657 |
Now, we try dividing 52,142,657 by 3:
52,142,657 ÷ 3 = 17,380,885.6667
If the quotient is a whole number, then 3 and 17,380,885.6667 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 | 52,142,657 | |
| -1 | -52,142,657 |
Let's try dividing by 4:
52,142,657 ÷ 4 = 13,035,664.25
If the quotient is a whole number, then 4 and 13,035,664.25 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 | 52,142,657 | |
| -1 | 52,142,657 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 109 | 259 | 763 | 1,847 | 4,033 | 12,929 | 28,231 | 68,339 | 201,323 | 478,373 | 1,409,261 | 7,448,951 | 52,142,657 |
| -1 | -7 | -37 | -109 | -259 | -763 | -1,847 | -4,033 | -12,929 | -28,231 | -68,339 | -201,323 | -478,373 | -1,409,261 | -7,448,951 | -52,142,657 |
