Classmate, didn't you listen well in class? What size is small? People call it power. Your 2 small 4, we usually call 2 4 on the computer. You asked for the least common multiple, right? Shouldn't the least common multiple be enclosed in brackets? But if you use (), I also use this.

Ok, here are some boring questions for you:

144=2^4*3^2, 120=2^3*3*5, ( 144, 120)=2^4*3^2*5=720;

192=2^6*3, 256=2^8, ( 192, 256)=2^8*3=768;

2 16=2^3*3^3, 396=2^2*3^2* 1 1, (2 16, 396)=2^3*3^3* 1 1=2376;

150=2*3*5^2, 200=2^3*5^2, ( 150, 200)=2^3*3*5^2=600;

360=2^3*3^2*5, 240=2^4*3*5, (360, 240)=2^4*3^2*5=720;

300=2^3*3*5^2, 160=2^5*5, (300, 160)=2^5*3*5^2=2400;

16=2^4, 18=2*3^2, 40=2^3*5, ( 16, 18, 40)=2^4*3^2*5=720;

30=2*3*5, 24=2^3*3, 36=2^2*3^2, (30, 24, 36)=2^3*3^2*5=360;

54=2*3^3, 8 1=3^4, 42=2*3*7, (54, 8 1, 42)=2*3^4*7= 1 134;

24=2^3*3, 36=2^2*3^2, 54=2*3^3, (24, 36, 54)=2^3*3^3=2 16;

32=2^5, 20=2^2*5, 50=2*5^2, (32, 20, 50)=2^5*5^2=800;

45=3^2*5, 27=3^3, 42=2*3*7, (45, 27, 42)=2*3^3*5*7= 1890。

Oh, my God, I'm exhausted. So many problems have been solved.
