GCF of 10 and 11
1
LCM of 10 and 11
110
How it works
Break each number into its prime factors:
- 10 = 2 × 5
- 11 = 11
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (110) multiplies every prime that appears in either number, at the highest power — which is also 10 × 11 ÷ 1 = 110.
