LCM( 19, 93 ) = 1767
Step 1: Write down factorisation of each number:
19 = 19
93 = 3 · 31
Step 2 : Match primes vertically:
19 | = | 19 | ||||
93 | = | 3 | · | 31 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
19 | = | 19 | ||||||
93 | = | 3 | · | 31 | ||||
LCM | = | 3 | · | 19 | · | 31 | = | 1767 |
