Two neon signs are turned on at the same time. One blinks every 12 seconds. The other blinks every 15 seconds. In how many seconds will they both blink at the same time?
The answer is simply the Lowest Common Multiples between the two number 12 and 15, which will be 2 x 2 x 3 x 5 = 60
Another way to prove this is that at 60 seconds, the 12 seconds sign would have blinked 60 ÷ 12 = 5 times while the 15 seconds sign would have blinked 60 ÷ 15 = 4 times.

Should I buy bitcoin?
“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
