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 factors of larger numbers. To find the factors of the number 32,728,407, it is easiest to start from the outside in. Here's what we mean:
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.
| 1 | 32,728,407 |
Next, we take the number 32,728,407 and divide it by 2.
In this case, 32,728,407 ÷ 2 = 16,364,203.5
If the quotient is a whole number, then 2 and 16,364,203.5 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
| 1 | 32,728,407 |
Now, we try dividing 32,728,407 by 3.
32,728,407 ÷ 3 = 10,909,469
If the quotient is a whole number, then 3 and 10,909,469 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
Here is what our table should look like at this step:
| 1 | 3 | 10,909,469 | 32,728,407 |
Let's try dividing by 4.
32,728,407 ÷ 4 = 8,182,101.75
If the quotient is a whole number, then 4 and 8,182,101.75 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
Here is what our table should look like at this step:
| 1 | 3 | 10,909,469 | 32,728,407 |
We keep dividing by the next largest number, in this case the number 5. If the quotient of 32,728,407 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.
Keep dividing by the next highest number until you cannot divide anymore.
What you will end up with is this table:
| 1 | 3 | 743 | 2,229 | 14,683 | 44,049 | 10,909,469 | 32,728,407 |
All of the numbers in the table above can be evenly divided into the number 32,728,407.
Finally, for your reference, here are all of the divisor combinations of the number 32,728,407:
1 x 32728407
3 x 10909469
743 x 44049
