LCM( 19, 95 ) = 95
Step 1: Write down factorisation of each number:
19 = 19
95 = 5 · 19
Step 2 : Match primes vertically:
19 | = | 19 | ||
95 | = | 5 | · | 19 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
19 | = | 19 | ||||
95 | = | 5 | · | 19 | ||
LCM | = | 5 | · | 19 | = | 95 |
