Find Least Common Multiple of 3, 5, 3 and 3 using prime factorisation method.
Answer
LCM( 3, 5, 3, 3 ) = 15
Explanation
Step 1: Write down factorisation of each number:
3 = 3
5 = 5
3 = 3
3 = 3
Step 2 : Match primes vertically:
| 3 | = | 3 | ||
| 5 | = | 5 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
| 3 | = | 3 | ||||
| 5 | = | 5 | ||||
| LCM | = | 3 | · | 5 | = | 15 |
