LCM of 11 and 17
187
How it works
Break each number into its prime factors:
- 11 = 11
- 17 = 17
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (187) multiplies every prime that appears in either number, at the highest power — which is also 11 × 17 ÷ 1 = 187.
