Answer:
Hi friends
Step-by-step explanation:
lcm of 2,6,10 is 30
30/3=10
10 second
Step-by-step explanation:
We need to find the LCM of 2, 6 &10
Prime factorization of :-
2 = 2 × 1
6 = 2 × 2 × 2 × 1
10 = 2 × 5 × 1
( In all the prime factors of these numbers, 2 & 1 are occurring the same. So we can skip those numbers and multiply the rest to get the LCM )
= 2 × 2 × 5
= 20
LCM = 20
Hence, if they ring together it takes 20 seconds.
Hope it helps!!!
