LCM( 6858, 4979 ) = 34145982
Step 1: Write down factorisation of each number:
6858 = 2 · 3 · 3 · 3 · 127
4979 = 13 · 383
Step 2 : Match primes vertically:
6858 | = | 2 | · | 3 | · | 3 | · | 3 | · | 127 | ||||
4979 | = | 13 | · | 383 |
Step 3 : Bring down numbers in each column and multiply to get LCM:
6858 | = | 2 | · | 3 | · | 3 | · | 3 | · | 127 | ||||||
4979 | = | 13 | · | 383 | ||||||||||||
LCM | = | 2 | · | 3 | · | 3 | · | 3 | · | 13 | · | 127 | · | 383 | = | 34145982 |
