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 57,506,075, 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 | 57,506,075 | |
| -1 | -57,506,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,506,075.
Example:
1 x 57,506,075 = 57,506,075
and
-1 x -57,506,075 = 57,506,075
Notice both answers equal 57,506,075
With that explanation out of the way, let's continue. Next, we take the number 57,506,075 and divide it by 2:
57,506,075 ÷ 2 = 28,753,037.5
If the quotient is a whole number, then 2 and 28,753,037.5 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 | 57,506,075 | |
| -1 | -57,506,075 |
Now, we try dividing 57,506,075 by 3:
57,506,075 ÷ 3 = 19,168,691.6667
If the quotient is a whole number, then 3 and 19,168,691.6667 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 | 57,506,075 | |
| -1 | -57,506,075 |
Let's try dividing by 4:
57,506,075 ÷ 4 = 14,376,518.75
If the quotient is a whole number, then 4 and 14,376,518.75 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 | 57,506,075 | |
| -1 | 57,506,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 79 | 275 | 395 | 869 | 1,975 | 2,647 | 4,345 | 13,235 | 21,725 | 29,117 | 66,175 | 145,585 | 209,113 | 727,925 | 1,045,565 | 2,300,243 | 5,227,825 | 11,501,215 | 57,506,075 |
| -1 | -5 | -11 | -25 | -55 | -79 | -275 | -395 | -869 | -1,975 | -2,647 | -4,345 | -13,235 | -21,725 | -29,117 | -66,175 | -145,585 | -209,113 | -727,925 | -1,045,565 | -2,300,243 | -5,227,825 | -11,501,215 | -57,506,075 |
