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 153,425,341, 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 | 153,425,341 | |
| -1 | -153,425,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,425,341.
Example:
1 x 153,425,341 = 153,425,341
and
-1 x -153,425,341 = 153,425,341
Notice both answers equal 153,425,341
With that explanation out of the way, let's continue. Next, we take the number 153,425,341 and divide it by 2:
153,425,341 ÷ 2 = 76,712,670.5
If the quotient is a whole number, then 2 and 76,712,670.5 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 | 153,425,341 | |
| -1 | -153,425,341 |
Now, we try dividing 153,425,341 by 3:
153,425,341 ÷ 3 = 51,141,780.3333
If the quotient is a whole number, then 3 and 51,141,780.3333 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 | 153,425,341 | |
| -1 | -153,425,341 |
Let's try dividing by 4:
153,425,341 ÷ 4 = 38,356,335.25
If the quotient is a whole number, then 4 and 38,356,335.25 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 | 153,425,341 | |
| -1 | 153,425,341 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 73 | 137 | 529 | 667 | 1,679 | 2,117 | 3,151 | 3,973 | 10,001 | 15,341 | 38,617 | 48,691 | 72,473 | 91,379 | 230,023 | 290,029 | 1,119,893 | 2,101,717 | 5,290,529 | 6,670,667 | 153,425,341 |
| -1 | -23 | -29 | -73 | -137 | -529 | -667 | -1,679 | -2,117 | -3,151 | -3,973 | -10,001 | -15,341 | -38,617 | -48,691 | -72,473 | -91,379 | -230,023 | -290,029 | -1,119,893 | -2,101,717 | -5,290,529 | -6,670,667 | -153,425,341 |
