Find Least Common Multiple of 91, 182, 455 and 273 using prime factorisation method.
Answer
LCM( 91, 182, 455, 273 ) = 2730
Explanation
Step 1: Write down factorisation of each number:
91 = 7 · 13
182 = 2 · 7 · 13
455 = 5 · 7 · 13
273 = 3 · 7 · 13
Step 2 : Match primes vertically:
| 91 | = | 7 | · | 13 | ||||||
| 182 | = | 2 | · | 7 | · | 13 | ||||
| 455 | = | 5 | · | 7 | · | 13 | ||||
| 273 | = | 3 | · | 7 | · | 13 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
| 91 | = | 7 | · | 13 | ||||||||
| 182 | = | 2 | · | 7 | · | 13 | ||||||
| 455 | = | 5 | · | 7 | · | 13 | ||||||
| 273 | = | 3 | · | 7 | · | 13 | ||||||
| LCM | = | 2 | · | 3 | · | 5 | · | 7 | · | 13 | = | 2730 |
