LCM( 2055, 815 ) = 334965
Step 1: Write down factorisation of each number:
2055 = 3 · 5 · 137
815 = 5 · 163
Step 2 : Match primes vertically:
2055 | = | 3 | · | 5 | · | 137 | ||
815 | = | 5 | · | 163 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
2055 | = | 3 | · | 5 | · | 137 | ||||
815 | = | 5 | · | 163 | ||||||
LCM | = | 3 | · | 5 | · | 137 | · | 163 | = | 334965 |
