Answer:

I guess 56 seconds is the answer.

Step-by-step explanation:

green light glows after 12 seconds

red light glows after EVERY 30 seconds, so it'll glow (30-12=18) seconds after green light.

blue light glows after EVERY 34 seconds, that'd be (34-30=4) seconds after red light

yellow light glows after EVERY 56 seconds, that means (56-34=22) seconds after blue light

So, in all the least minutes after which they all glow together = 12 + 18 + 4 + 22

=56 seconds

                                   

Hope you got this!
