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 712,075, 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 | 712,075 | |
| -1 | -712,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 712,075.
Example:
1 x 712,075 = 712,075
and
-1 x -712,075 = 712,075
Notice both answers equal 712,075
With that explanation out of the way, let's continue. Next, we take the number 712,075 and divide it by 2:
712,075 ÷ 2 = 356,037.5
If the quotient is a whole number, then 2 and 356,037.5 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 | 712,075 | |
| -1 | -712,075 |
Now, we try dividing 712,075 by 3:
712,075 ÷ 3 = 237,358.3333
If the quotient is a whole number, then 3 and 237,358.3333 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 | 712,075 | |
| -1 | -712,075 |
Let's try dividing by 4:
712,075 ÷ 4 = 178,018.75
If the quotient is a whole number, then 4 and 178,018.75 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 | 712,075 | |
| -1 | 712,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 313 | 325 | 455 | 1,565 | 2,191 | 2,275 | 4,069 | 7,825 | 10,955 | 20,345 | 28,483 | 54,775 | 101,725 | 142,415 | 712,075 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -313 | -325 | -455 | -1,565 | -2,191 | -2,275 | -4,069 | -7,825 | -10,955 | -20,345 | -28,483 | -54,775 | -101,725 | -142,415 | -712,075 |
