1.	1. There is a circular path around a sports field. Sonia takes 18 minutes to drive one roundof the field, while Ravi takes 12 minutes for the same. Suppose they both start at thesame point and at the same time, and go in the same direction. After how many minuteswill they meet again at the starting point? ... why we find lcm in this question please clear .
Answer» The time of their meet is the LCM of the TIMES taken. We will find the LCM of 18 and 12 by prime factorisation method. factors of 18 = 2 × 3 × 3 factors of 12 = 2 × 2 × 3 common factors = 2 × 3 × 2 × 3 LCM = 36 SONIA and Ravi meet after 36 minutes. We use find LCM where: When the event will be REPEATING over and over again. To find out if something will happen again the same time. These are the things to remember when you find out LCM.

Answer»

The time of their meet is the LCM of the TIMES taken.

We will find the LCM of 18 and 12 by prime factorisation method.

factors of 18 = 2 × 3 × 3

factors of 12 = 2 × 2 × 3

common factors = 2 × 3 × 2 × 3

LCM = 36

SONIA and Ravi meet after 36 minutes.

We use find LCM where:
