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