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 326,761,525, 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 | 326,761,525 | |
| -1 | -326,761,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 326,761,525.
Example:
1 x 326,761,525 = 326,761,525
and
-1 x -326,761,525 = 326,761,525
Notice both answers equal 326,761,525
With that explanation out of the way, let's continue. Next, we take the number 326,761,525 and divide it by 2:
326,761,525 ÷ 2 = 163,380,762.5
If the quotient is a whole number, then 2 and 163,380,762.5 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 | 326,761,525 | |
| -1 | -326,761,525 |
Now, we try dividing 326,761,525 by 3:
326,761,525 ÷ 3 = 108,920,508.3333
If the quotient is a whole number, then 3 and 108,920,508.3333 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 | 326,761,525 | |
| -1 | -326,761,525 |
Let's try dividing by 4:
326,761,525 ÷ 4 = 81,690,381.25
If the quotient is a whole number, then 4 and 81,690,381.25 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 | 326,761,525 | |
| -1 | 326,761,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 71 | 95 | 355 | 475 | 1,349 | 1,775 | 6,745 | 9,689 | 33,725 | 48,445 | 184,091 | 242,225 | 687,919 | 920,455 | 3,439,595 | 4,602,275 | 13,070,461 | 17,197,975 | 65,352,305 | 326,761,525 |
| -1 | -5 | -19 | -25 | -71 | -95 | -355 | -475 | -1,349 | -1,775 | -6,745 | -9,689 | -33,725 | -48,445 | -184,091 | -242,225 | -687,919 | -920,455 | -3,439,595 | -4,602,275 | -13,070,461 | -17,197,975 | -65,352,305 | -326,761,525 |
