GCF of 9 and 14
1
LCM of 9 and 14
126
How it works
Break each number into its prime factors:
- 9 = 3²
- 14 = 2 × 7
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (126) multiplies every prime that appears in either number, at the highest power — which is also 9 × 14 ÷ 1 = 126.
