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 1,500,037, 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 | 1,500,037 | |
| -1 | -1,500,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,500,037.
Example:
1 x 1,500,037 = 1,500,037
and
-1 x -1,500,037 = 1,500,037
Notice both answers equal 1,500,037
With that explanation out of the way, let's continue. Next, we take the number 1,500,037 and divide it by 2:
1,500,037 ÷ 2 = 750,018.5
If the quotient is a whole number, then 2 and 750,018.5 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 | 1,500,037 | |
| -1 | -1,500,037 |
Now, we try dividing 1,500,037 by 3:
1,500,037 ÷ 3 = 500,012.3333
If the quotient is a whole number, then 3 and 500,012.3333 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 | 1,500,037 | |
| -1 | -1,500,037 |
Let's try dividing by 4:
1,500,037 ÷ 4 = 375,009.25
If the quotient is a whole number, then 4 and 375,009.25 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 | 1,500,037 | |
| -1 | 1,500,037 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 49 | 77 | 121 | 161 | 253 | 539 | 847 | 1,127 | 1,331 | 1,771 | 2,783 | 5,929 | 9,317 | 12,397 | 19,481 | 30,613 | 65,219 | 136,367 | 214,291 | 1,500,037 |
| -1 | -7 | -11 | -23 | -49 | -77 | -121 | -161 | -253 | -539 | -847 | -1,127 | -1,331 | -1,771 | -2,783 | -5,929 | -9,317 | -12,397 | -19,481 | -30,613 | -65,219 | -136,367 | -214,291 | -1,500,037 |
