This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 14 and 33.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 14 and 33
What to be found:
lcm (14, 33) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
14 and 33
step 3 Choose the divisor which divides each or most of the given integers (14 and 33), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if any integer in 14 and 33 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 14 | 33 |
| 3 | 7 | 33 |
| 7 | 7 | 11 |
| 11 | 1 | 11 |
| 1 | 1 |
