1
LCM of 10 and 17
170
How it works
Break each number into its prime factors:
- 10 = 2 × 5
- 17 = 17
The GCF (1) multiplies the primes both share, at the lowest power each appears. The LCM (170) multiplies every prime that appears in either number, at the highest power — which is also 10 × 17 ÷ 1 = 170.
