Find Least Common Multiple of 394 and 236 using prime factorisation method.
Answer
LCM( 394, 236 ) = 46492
Explanation
Step 1: Write down factorisation of each number:
394 = 2 · 197
236 = 2 · 2 · 59
Step 2 : Match primes vertically:
| 394 | = | 2 | · | 197 | ||||
| 236 | = | 2 | · | 2 | · | 59 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
| 394 | = | 2 | · | 197 | ||||||
| 236 | = | 2 | · | 2 | · | 59 | ||||
| LCM | = | 2 | · | 2 | · | 59 | · | 197 | = | 46492 |
This solution can be visualized using a Venn diagram.
The LCM is equal to the product of all the numbers on the diagram.
