LCM( 208, 439 ) = 91312
Step 1: Write down factorisation of each number:
208 = 2 · 2 · 2 · 2 · 13
439 = 439
Step 2 : Match primes vertically:
208 | = | 2 | · | 2 | · | 2 | · | 2 | · | 13 | ||
439 | = | 439 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
208 | = | 2 | · | 2 | · | 2 | · | 2 | · | 13 | ||||
439 | = | 439 | ||||||||||||
LCM | = | 2 | · | 2 | · | 2 | · | 2 | · | 13 | · | 439 | = | 91312 |
