Answer:
The LCM (Least Common Multiple) of 15 and 143 is 2,145
Step-by-step explanation:
List the first 10 multiples of 15 first. (or more)
15: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360,
Now for 143
143:143,286,429,572,715...
So their CM is 2,145
But maybe, it is not their LCM
