GCF of 11 and 14
1
LCM of 11 and 14
154
How it works
Break each number into its prime factors:
- 11 = 11
- 14 = 2 × 7
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (154) multiplies every prime that appears in either number, at the highest power — which is also 11 × 14 ÷ 1 = 154.
