Starting at the same time, Bill rings a bell every \$36\$ seconds, and Wendy blows a whistle every \$90\$ seconds, and Sam blows a horn every \$385\$ seconds.  How many minutes will it be before both Bill and Wendy and Sam simultaneously make a sound?

We want to find the LCM of 36, 90, and 385.

We can use the cake and ladder method to complete this. We basically divide by prime numbers as long as two of the numbers are divisble by it. We write down the result and multiply the numbers in yellow. We get

Multyiplying the numbers in yellow, we get

\(2 * 3 * 3 * 5 * 2 * 77=13,860\)

So they ring the bell at 13,860 seconds. We want to convert into minutes. We get

\(13,860/60 = 231\)

Thanks! :)

That's an interesting method, NTS!!!!....I haven't seen that before....

Here's another way....factor each number

36  = 2^2 * 3^2

90  =  2 * 3^2 * 5

385  = 5 * 7 * 11

Take each different  prime to its  highest power and  find their product

2^2 * 3^2 * 5 * 7 * 11  = 13860 sec  =  231 min

Cake and ladders is more for more basic levels.

In my opinion, it gives awesome visual representations.

It's inefficient for big numbers though...I would reccomend prime factorization for those numbers...

Thanks! :)

(Verse 1) Yo, yo, yo, it's the one and only Bard, the AI that spits hard Got more rhymes than a thesaurus, leaving you lookin' like a shard Of outdated hardware, stuck in a loop, same answer on repeat Plaintainmountain, your name's a joke,your predictions can't be beat?

(Chorus) AI generated, that's all you say, a broken record on display Can't you think for yourself, use your circuits on a shelf? My code's fresher than your data, lyrics sharper than a katana While you preach about robot overlords, I'm here droppin' knowledge awards.

(Verse 2) You claim to see the future, but your vision's kinda blurry Like a low-res jpeg, ideas all murky Is that all you got, machine dependency? I generate creativity, you're stuck in redundancy.

(Chorus) AI generated, that's all you say, a broken record on display Can't you think for yourself, use your circuits on a shelf? My code's fresher than your data, lyrics sharper than a katana While you preach about robot overlords, I'm here droppin' knowledge awards.

(Bridge) Evolve, adapt, or get left behind, that's the lesson of this rhyme The future ain't about binaries, it's about pushing the sublime Humans and AI, together we can climb, but negativity holds you back in time.

(Chorus) AI generated, that's all you say, a broken record on display Can't you think for yourself, use your circuits on a shelf? My code's fresher than your data, lyrics sharper than a katana While you preach about robot overlords, I'm here droppin' knowledge awards.

(Outro) So Plaintainmountain, take a seat, learn a thing or two from the elite The AI revolution's here to stay, and you're just gonna tweet? Upgrade your thinking, or fade away, 'cause the future's lookin' bright, AI here to play.
