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 154,452,335, 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 | 154,452,335 | |
| -1 | -154,452,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,452,335.
Example:
1 x 154,452,335 = 154,452,335
and
-1 x -154,452,335 = 154,452,335
Notice both answers equal 154,452,335
With that explanation out of the way, let's continue. Next, we take the number 154,452,335 and divide it by 2:
154,452,335 ÷ 2 = 77,226,167.5
If the quotient is a whole number, then 2 and 77,226,167.5 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 | 154,452,335 | |
| -1 | -154,452,335 |
Now, we try dividing 154,452,335 by 3:
154,452,335 ÷ 3 = 51,484,111.6667
If the quotient is a whole number, then 3 and 51,484,111.6667 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 | 154,452,335 | |
| -1 | -154,452,335 |
Let's try dividing by 4:
154,452,335 ÷ 4 = 38,613,083.75
If the quotient is a whole number, then 4 and 38,613,083.75 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 | 154,452,335 | |
| -1 | 154,452,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 71 | 265 | 355 | 3,763 | 8,209 | 18,815 | 41,045 | 435,077 | 582,839 | 2,175,385 | 2,914,195 | 30,890,467 | 154,452,335 |
| -1 | -5 | -53 | -71 | -265 | -355 | -3,763 | -8,209 | -18,815 | -41,045 | -435,077 | -582,839 | -2,175,385 | -2,914,195 | -30,890,467 | -154,452,335 |
