Answer :
Both the lights will flash together at 6:20 A.M.
What is L.C.M?
- LCM stands for least common multiple.
- The least common multiple of two numbers is the smallest number that is a multiple of both of them.
- We can calculate L.C.M as -
L.C.M {a, b} = {(a x b)/H.C.F {a, b})
Given is that Light M flashes every 4 minutes. Light N flashes every 10 minutes. At one point, lights flash together at 6:00 a.m.
The lowest common multiple of 4 and 10 is 20. So, the next time both the lights will flash at 6 : 20 A.M.
Therefore, both the lights will flash together at 6:20 A.M.
