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 376,782,565, 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 | 376,782,565 | |
| -1 | -376,782,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 376,782,565.
Example:
1 x 376,782,565 = 376,782,565
and
-1 x -376,782,565 = 376,782,565
Notice both answers equal 376,782,565
With that explanation out of the way, let's continue. Next, we take the number 376,782,565 and divide it by 2:
376,782,565 ÷ 2 = 188,391,282.5
If the quotient is a whole number, then 2 and 188,391,282.5 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 | 376,782,565 | |
| -1 | -376,782,565 |
Now, we try dividing 376,782,565 by 3:
376,782,565 ÷ 3 = 125,594,188.3333
If the quotient is a whole number, then 3 and 125,594,188.3333 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 | 376,782,565 | |
| -1 | -376,782,565 |
Let's try dividing by 4:
376,782,565 ÷ 4 = 94,195,641.25
If the quotient is a whole number, then 4 and 94,195,641.25 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 | 376,782,565 | |
| -1 | 376,782,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 73 | 265 | 365 | 3,869 | 19,345 | 19,477 | 97,385 | 1,032,281 | 1,421,821 | 5,161,405 | 7,109,105 | 75,356,513 | 376,782,565 |
| -1 | -5 | -53 | -73 | -265 | -365 | -3,869 | -19,345 | -19,477 | -97,385 | -1,032,281 | -1,421,821 | -5,161,405 | -7,109,105 | -75,356,513 | -376,782,565 |
