Find Least Common Multiple of 5 and 5 using prime factorisation method.
Answer
LCM( 5, 5 ) = 5
Explanation
Step 1: Write down factorisation of each number:
5 = 5
5 = 5
Step 2 : Match primes vertically:
| 5 | = | 5 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
| 5 | = | 5 | ||
| LCM | = | 5 | = | 5 |
This solution can be visualized using a Venn diagram.
