GCF of 44 and 66
22
LCM of 44 and 66
132
How it works
Break each number into its prime factors:
- 44 = 2² × 11
- 66 = 2 × 3 × 11
The GCF (22) multiplies the primes both share, at the lowest power each appears. The LCM (132) multiplies every prime that appears in either number, at the highest power — which is also 44 × 66 ÷ 22 = 132.
