LCM of 6 and 17
102
How it works
Break each number into its prime factors:
- 6 = 2 × 3
- 17 = 17
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (102) multiplies every prime that appears in either number, at the highest power — which is also 6 × 17 ÷ 1 = 102.
