LCM of 2 and 4 Related Examples
Some examples related to LCM of 2 and 4 are,
Example 1: A train departs every 2 hours and another train departs every 4 hours. What is the minimum time interval after which both trains will depart the station again at the same time?
Solution:
Minimum time interval after which both train depart at same time from station is the LCM their time interval
LCM of 2 and 4 is 4
Therefore, after 4 hours, both trains will depart again at the same time.
Example 2: What is the smallest number that is divisible by 2 and 4 exactly?
Solution:
Smallest number that is divisible by 2 and 4 exactly is their LCM
LCM of 2 and 4 is calculted by listing multiples of 2 and 4
- Multiples of 2 = 2, 4, 6, 8, 10, 12, 14, . . . .
- Multiples of 4 = 4, 8, 12, 16, 20, 24, 28, . . . .
Smallest common multiple as checked from above multiple list is 4. Therefore, the LCM of 2 and 4 is 4.
Example 3: If the LCM of 2 and 4 is 4, then find its GCF.
Solution:
We know that,
LCM of 2 and 4 × GCF of 2 and 4 = 2 × 4
4 × GCF of 2 and 4 = 8
GCF of 2 and 4 = 8/4 = 2
