Answer:

<em>The answer is 56 seconds.</em>

Step-by-step explanation:

<em>In this example,  if two lights at a local stadium are flickering, and at the same time they flicked. both at the same time. and again, one of the lights flickers at every 8 seconds with the other at 7 seconds.</em>

<em>Then,</em>

<em>We apply the lowest common multiple between the two lights.</em>

<em>Furthermore, the LCM refers to the actual numbers multiplied by each of the lights that flicked together.</em>

<em>Therefore the number of seconds till both lights will flicker at same time is </em>

<em>7 * 8 = 56 seconds.</em>

You need to find the first common multiple of both 7 and 8. In this case, the LCM (lowest common multiple) is actually the numbers multiplies by each other, or 56. So the answer is 56 seconds

Hope this helps
