Which of the following concept (s) is used to find the time after which they will meet again? (1) Least Common Multiple (2) Prime factorisation (3) Both A and B (4) Highest Common Factor

Note- I don't need solution jist please mention which method have you used to solve this question from above mentioned methods​

Answer 1

Answer:

answer by brainlist

Step-by-step explanation:

Then there is no common prime factor in 18 and 12, so there is no effect on LCM. So, LCM of 18 and 12 is 36. That means the time taken by Ravi and Sonia to meet again at the starting point is 36 minutes. ... Ravi takes 12 minutes to drive one round around the field.

Answer 2

Right answer is option (1)Least Common Multiple
