GCF of 11 and 16
1
LCM of 11 and 16
176
How it works
Break each number into its prime factors:
- 11 = 11
- 16 = 2⁴
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (176) multiplies every prime that appears in either number, at the highest power — which is also 11 × 16 ÷ 1 = 176.
