LCM( 276, 184, 230 ) = 2760
Step 1: Write down factorisation of each number:
276 = 2 · 2 · 3 · 23
184 = 2 · 2 · 2 · 23
230 = 2 · 5 · 23
Step 2 : Match primes vertically:
276 | = | 2 | · | 2 | · | 3 | · | 23 | ||||
184 | = | 2 | · | 2 | · | 2 | · | 23 | ||||
230 | = | 2 | · | 5 | · | 23 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
276 | = | 2 | · | 2 | · | 3 | · | 23 | ||||||
184 | = | 2 | · | 2 | · | 2 | · | 23 | ||||||
230 | = | 2 | · | 5 | · | 23 | ||||||||
LCM | = | 2 | · | 2 | · | 2 | · | 3 | · | 5 | · | 23 | = | 2760 |
