Answer 1

Answer:

Hi friends

Step-by-step explanation:

lcm of 2,6,10 is 30

30/3=10

10 second

Answer 2

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!!!
