Answer the real-world problem below. Then, decide whether the answer is the GCF or the LCM. A local radio station is celebrating its 10th year on the air and is giving away prizes to callers. It is giving away a $10 bill for every 10th caller. It is also giving away free digital albums to every 8th caller. How many callers will call the radio station until someone wins both a $10 bill and a free digital album?

Step-by-step explanation:

The solution  is  LCM

the least common multiple of 10 and 8 are

10=10,20,30,40,50,60,70,80,90,

8= 8,16,24,32,40,48,56,64,72,80,88

The least common multiple is 80

therefore it will take 80 callers to call in to win both the bills

kindly let me know if you need further clarification on this
