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 145,683,355, 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 | 145,683,355 | |
| -1 | -145,683,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,683,355.
Example:
1 x 145,683,355 = 145,683,355
and
-1 x -145,683,355 = 145,683,355
Notice both answers equal 145,683,355
With that explanation out of the way, let's continue. Next, we take the number 145,683,355 and divide it by 2:
145,683,355 ÷ 2 = 72,841,677.5
If the quotient is a whole number, then 2 and 72,841,677.5 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 | 145,683,355 | |
| -1 | -145,683,355 |
Now, we try dividing 145,683,355 by 3:
145,683,355 ÷ 3 = 48,561,118.3333
If the quotient is a whole number, then 3 and 48,561,118.3333 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 | 145,683,355 | |
| -1 | -145,683,355 |
Let's try dividing by 4:
145,683,355 ÷ 4 = 36,420,838.75
If the quotient is a whole number, then 4 and 36,420,838.75 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 | 145,683,355 | |
| -1 | 145,683,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 361 | 817 | 1,805 | 1,877 | 4,085 | 9,385 | 15,523 | 35,663 | 77,615 | 80,711 | 178,315 | 403,555 | 677,597 | 1,533,509 | 3,387,985 | 7,667,545 | 29,136,671 | 145,683,355 |
| -1 | -5 | -19 | -43 | -95 | -215 | -361 | -817 | -1,805 | -1,877 | -4,085 | -9,385 | -15,523 | -35,663 | -77,615 | -80,711 | -178,315 | -403,555 | -677,597 | -1,533,509 | -3,387,985 | -7,667,545 | -29,136,671 | -145,683,355 |
