Time taken by first person to jog one round= 12 min
Time taken by second person to jog one round= 18 min
The LCM of 18 and 12 gives the exact number of minutes after which they will meet at the starting point again.
The required time = LCM of 12 and 18 minutes.
Prime factorisation of 12 and 18 are:
12 = 2 × 2 ×3
18 = 2 × 3 ×3
LCM (12, 18) = 2× 2× 3 × 3 = 36
Hence,the two persons will meet again at the starting point after 36 minutes.

ANSWER
..........
1ST PERSON TIME = 12 MIN
2ND PERSON TIME = 18 MINUTES
THEREFORE THE FACTOR OF 12 AND 18.
12 = 2*2*3
18 = 2*3*3
THEREFORE
2*2*3*3
