GCF of 2 and 11
1
LCM of 2 and 11
22
How it works
Break each number into its prime factors:
- 2 = 2
- 11 = 11
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (22) multiplies every prime that appears in either number, at the highest power — which is also 2 × 11 ÷ 1 = 22.
