LCM( 1, 1 ) = 1
Step 1: Write down factorisation of each number:
1 = 1
1 = 1
Step 2 : Match primes vertically:
1 | = | 1 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
1 | = | 1 | ||
LCM | = | 1 | = | 1 |
This solution can be visualized using a Venn diagram.
The LCM is equal to the product of all the numbers on the diagram.
