LCM( 24, 82, 50 ) = 24600
Step 1: Write down factorisation of each number:
24 = 2 · 2 · 2 · 3
82 = 2 · 41
50 = 2 · 5 · 5
Step 2 : Match primes vertically:
24 | = | 2 | · | 2 | · | 2 | · | 3 | ||||||
82 | = | 2 | · | 41 | ||||||||||
50 | = | 2 | · | 5 | · | 5 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
24 | = | 2 | · | 2 | · | 2 | · | 3 | ||||||||
82 | = | 2 | · | 41 | ||||||||||||
50 | = | 2 | · | 5 | · | 5 | ||||||||||
LCM | = | 2 | · | 2 | · | 2 | · | 3 | · | 5 | · | 5 | · | 41 | = | 24600 |
