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 57,291,275, 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 | 57,291,275 | |
| -1 | -57,291,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,291,275.
Example:
1 x 57,291,275 = 57,291,275
and
-1 x -57,291,275 = 57,291,275
Notice both answers equal 57,291,275
With that explanation out of the way, let's continue. Next, we take the number 57,291,275 and divide it by 2:
57,291,275 ÷ 2 = 28,645,637.5
If the quotient is a whole number, then 2 and 28,645,637.5 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 | 57,291,275 | |
| -1 | -57,291,275 |
Now, we try dividing 57,291,275 by 3:
57,291,275 ÷ 3 = 19,097,091.6667
If the quotient is a whole number, then 3 and 19,097,091.6667 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 | 57,291,275 | |
| -1 | -57,291,275 |
Let's try dividing by 4:
57,291,275 ÷ 4 = 14,322,818.75
If the quotient is a whole number, then 4 and 14,322,818.75 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 | 57,291,275 | |
| -1 | 57,291,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 25 | 85 | 115 | 391 | 425 | 575 | 1,955 | 5,861 | 9,775 | 29,305 | 99,637 | 134,803 | 146,525 | 498,185 | 674,015 | 2,291,651 | 2,490,925 | 3,370,075 | 11,458,255 | 57,291,275 |
| -1 | -5 | -17 | -23 | -25 | -85 | -115 | -391 | -425 | -575 | -1,955 | -5,861 | -9,775 | -29,305 | -99,637 | -134,803 | -146,525 | -498,185 | -674,015 | -2,291,651 | -2,490,925 | -3,370,075 | -11,458,255 | -57,291,275 |
